Arm numbness is a neurological condition characterized by a tingling, pinprick, numbness or burning sensation in the arm. This sensation often develops as a result of nerve compression, injury or impaired blood circulation. Arm numbness may be temporary or it may be a sign of a chronic health problem.
Contents
Arm numbness can often start in one area (e.g. the hand, elbow or shoulder) and spread to the whole arm over time. Conditions that affect the functioning of the nervous system play an important role in the occurrence of this numbness. Cervical herniated discs or spinal problems can also cause arm numbness, especially as the nerves from the neck extend to the arm.
Individuals with arm numbness often experience the following complaints:
- Tingling in the fingers or wrist
- Full or partial numbness in the arm
- Decreased control of the hand or arm
- Sudden sensations similar to electric shock
- Mild pulling or weakness in the muscles
These symptoms may be short-term and transient, or they may be long-term symptoms indicating serious nerve damage. In particular, recurring arm numbness should not be neglected as it may indicate an underlying disease.
Arm numbness can be related not only to nerves, but also to blood vessels, muscles, bones and connective tissues. Therefore, a multidisciplinary evaluation is required to make the correct diagnosis. The cause of arm numbness should be investigated with physical examination, detailed patient history and advanced imaging techniques if necessary.
Why does arm numbness occur?
The question of why arm numbness occurs is an important issue that many people who experience this condition frequently seek the answer to. Arm numbness can occur when there is a problem with the nervous system or when the blood flow to the arm area is impaired. This condition may be caused by temporary and harmless causes or may indicate serious health problems.
The most common causes of arm numbness include pinched nerves. Conditions such as carpal tunnel syndrome or neck hernia, especially in the wrist, cause pressure on the nerves, leading to arm numbness. Similarly, nerve compression in the shoulder and elbow area can cause similar symptoms.
In some cases, arm numbness can be caused by circulatory system-related causes. Staying in the same position for a long time or lying on the arm causes the blood vessels to compress and blood flow to slow down. This leads to temporary arm numbness. However, a persistent disturbance in blood circulation can be a sign of more serious diseases.
Other causes of arm numbness include the following:
Vitamin deficiencies: Vitamin B12, B6 and D deficiencies in particular impair the health of the nervous system and cause arm numbness.
Diabetes: Diabetes can cause damage to peripheral nerves, leading to numbness in the arm.
Multiple Sclerosis (MS): This disease, which affects the central nervous system, can manifest itself with neurological symptoms such as arm numbness.
Thyroid diseases: Hormone disorders such as hypothyroidism can slow nerve conduction.
Rheumatic diseases: Inflammation of the joints can cause nerves to be under pressure.
Trauma: Strokes or sprains to the arm can cause nerve damage.
Arm numbness can also have psychological causes. In cases such as prolonged stress, anxiety or panic attacks, people may experience numbness, tingling or burning sensation in their arms.
The answer to the question of why arm numbness occurs may be different for each individual. Therefore, a specialist examination is essential for accurate diagnosis.

Why does left arm numbness occur?
Left arm numbness can be a symptom of serious conditions that can be life-threatening in some cases. Especially in cases that require emergency intervention such as heart attack, left arm numbness is one of the most common symptoms. However, left arm numbness does not always mean a heart-related problem. Nervous system diseases, musculoskeletal problems and circulatory disorders can also cause numbness in the left arm.
One of the main causes of numbness in the left arm is nerve compression. Since the nerves coming out of the neck extend to the shoulders, arms and fingers, cervical herniated discs or cervical spine problems can cause numbness in the left arm. In particular, neck flattening or disc deformations can be manifested by numbness spreading to the left arm.
In addition, mechanical stresses such as blows to the upper left arm, working in the same position for a long time or lying on the arm can also cause arm numbness. In such cases, the numbness is usually temporary and disappears in a short time after changing the position.
However, if left arm numbness is accompanied by the following conditions, urgent medical attention may be needed:
- Feeling of tightness or pain in the chest
- Shortness of breath
- Pain radiating to the jaw and back
- Cold sweating
- Dizziness or nausea
Left arm numbness associated with these symptoms may be a sign of a heart attack. In such a case, the 112 Emergency Service should be contacted immediately.
Left arm numbness may also be associated with
- Neurological diseases such asMultiple Sclerosis (MS)
- Impaired nerve conduction due tovitamin B12 deficiency
- Thoracic outlet syndrome
- Cervical radiculopathy
- Rheumatic diseases
Left arm numbness should be evaluated in a wide range of conditions, from heart attack to nerve damage. In recurrent or prolonged left arm numbness, you should definitely consult a doctor.
How Does Arm Numbness Go Away?
The answer to the question of how arm numbness goes away depends on what causes this condition. If arm numbness is temporary, that is, a condition that occurs depending on the position, it can disappear in a short time with simple applications. However, in chronic or recurrent arm numbness, the underlying cause should be determined and a treatment plan should be applied accordingly.
If position-related arm numbness has developed due to, for example, lying on the arm for a long time or standing still at a desk, it can be relieved by the following methods:
- Changing the position: Reducing the pressure on the arm allows the nerves and blood vessels to relax.
- Doing light exercises: Finger and wrist movements can support nerve conduction and relieve arm numbness.
- Massage and warm application: Helps relax the muscles and improves circulation.
- Rest: In temporary numbness caused by overuse of the arm, a few hours of rest is often sufficient.
However, these methods alone may not be sufficient for arm numbness that persists for a long time or is felt with increasing severity. In this case, a specialist should be consulted and the necessary diagnostic tests should be performed. Arm numbness should be taken seriously, especially if it is accompanied by the following symptoms
- Loss of strength in the hand or arm
- Muscle wasting
- Inability of the hand to grasp objects
- Numbness severe enough to wake you up at night
- Arm numbness is associated with life-threatening conditions such as heart attack or stroke
Chronic arm numbness often requires a multifaceted approach, including physiotherapy, medication, vitamin support and lifestyle changes. Especially when vitamin B deficiencies are corrected, nerve conduction improves and complaints of arm numbness may decrease.
If arm numbness persists, specific treatment may be required depending on the cause. For this reason, it is absolutely necessary to consult a doctor in prolonged cases.
Which diseases may be associated with arm numbness?
Numbness in the arms is a symptom that can occur when many different systems in the body are affected. Especially diseases related to the nervous system, vascular structure and musculoskeletal system can cause arm numbness. Although arm numbness is sometimes due to simple and temporary causes, in some cases it can be the first sign of serious diseases.
Arm numbness may be directly related to the following diseases:
Herniated Cervical Disc (Cervical Disc Hernia)
Compression of the nerves by the discs in the cervical vertebrae usually causes one-sided arm numbness. It may also be associated with arm pain, decreased muscle strength and restricted movement.
Carpal Tunnel Syndrome
It is caused by compression of the median nerve passing through the wrist. Arm numbness, especially from the wrist to the hand and fingers, may increase at night. It is often seen in desk workers and people with repetitive hand movements.
Multiple Sclerosis (MS)
An autoimmune disease affecting the central nervous system, MS can lead to numbness, tingling, weakness and balance problems in various parts of the body, including the arms.
Diabetic Neuropathy
In long-term diabetic patients, nerve endings can be damaged, causing arm numbness. This condition usually manifests itself with widespread tingling and loss of sensation in both arms.
Rheumatoid Arthritis
This rheumatic disease, which causes inflammation of the joints, can cause arm numbness by causing nerves to be under pressure, especially in areas such as the wrist, elbow and shoulder.
Lupus
In this disease, in which the immune system attacks its own tissues, nerves and blood vessels can be affected. This can manifest itself as numbness and weakness in the arms.
Tarsal or Thoracic Outlet Syndrome
It occurs as a result of compression of the nerves going to the arm in the shoulder and chest area. It is especially common in individuals who carry heavy objects or experience constant tension around the shoulder.
Arm numbness may be a harbinger of these diseases. Medical evaluation is essential, especially for persistent, recurrent or increasing arm numbness.
Diagnosis of Numbness in the Arms and Tests Performed
Since numbness in the arms can occur for different reasons, it is extremely important to make the correct diagnosis. Patients who consult a doctor with the complaint of arm numbness undergo a physical examination and further tests. During this process, the patient's history, duration, severity and other accompanying symptoms are carefully evaluated.
The methods used in the diagnosis of arm numbness are aimed at identifying the source of the problem. Possibilities related to the nervous, muscular, vascular and spinal systems are tested.
Physical Examination
The physician first assesses the site of onset and extent of arm numbness. Muscle strength, reflexes, sensory responses and movement limitations are checked. This initial evaluation can tell to a large extent whether the arm numbness is due to neck origin, nerve compression or a systemic disease.
EMG (Electromyography)
The EMG test measures the electrical signals transmitted by nerves to muscles. This test can detect nerve compression, nerve conduction disorders and muscle diseases. It is one of the most commonly performed diagnostic tests in individuals with arm numbness.
Nerve Conduction Velocity (NCV)
This test measures how fast nerves transmit signals. If there is a slowing of the nerve, this can help to locate impingement or damage. It is applied together with EMG.
Magnetic Resonance Imaging (MRI)
MRI imaging allows a detailed examination of the cervical vertebrae, disc structures, spinal cord and nerve roots. Structural disorders that may cause arm numbness, such as cervical hernia or cervical stenosis, are clearly seen.
Computed Tomography (CT)
As an alternative to MR imaging, CT can also be used in some cases. In particular, changes in the bone structures of the spine are detected with this method.
Blood tests
Various blood tests are performed for vitamin deficiencies (especially B12, D and folic acid), diabetes, inflammatory diseases and hormone imbalances. If arm numbness is a symptom of a systemic disease, these tests play a major role in the diagnosis.
The correct diagnosis of arm numbness is the first and most important step for an effective treatment plan. For this reason, detailed examinations should be carried out in the presence of a specialist doctor.
Treatment of numbness in the arms and methods applied
Treatment of numbness in the arms is planned according to the underlying problem causing this symptom. If arm numbness is temporary and position-related, it may resolve spontaneously with simple lifestyle changes. However, if there is nerve compression, spinal problems or a systemic disease, more extensive treatment may be required.
The aim of arm numbness treatment is to remove the pressure on the nerve, repair the damage and prevent its recurrence. Therefore, the methods to be applied should be personalized.
Physical Therapy and Rehabilitation
Physical therapy is one of the most commonly used methods in the treatment of arm numbness. Special exercise programs and electrotherapy methods, especially for numbness due to pinched nerves, reduce the pressure on the nerve, strengthen the muscles and support circulation.
- Stretching and stretching exercises
- Strengthening neck, shoulder and arm muscles
- Tens, ultrasound and hot applications
- Manual therapy and mobilization techniques
Medication Therapy
In some cases, arm numbness can be controlled with medication. Depending on the condition causing numbness, the doctor may prescribe the following medications
- Vitamin B12 and complex vitamin B supplements
- Anti-inflammatory drugs (for inflammation and edema)
- Muscle relaxants
- Neuropathic pain medications (gabapentin, pregabalin, etc.)
Drug treatment is more effective when combined with physical therapy.
Lifestyle Changes
- Avoid staying in the same position for long periods of time
- Creating an ergonomic working environment
- Correcting sleep position
- Supporting the arm and wrist during computer and phone use
- Avoiding stress and practicing relaxation techniques
These measures both reduce the existing complaints of arm numbness and prevent recurrence.
Surgical Intervention
Surgical intervention may be necessary if the cause of arm numbness is a serious nerve compression, hernia or anatomical disorder. In particular, structural problems such as carpal tunnel syndrome, cervical hernia or thoracic outlet syndrome can be treated surgically. After surgery, physical therapy is usually applied in a supportive manner.
Alternative and Supportive Methods
Some patients benefit from the following alternative methods in addition to conventional treatments:
- Acupuncture
- Reflexology
- Ozone therapy
- Neural Therapy
- Functional medicine applications
Treatment of arm numbness should be planned individually and managed by a qualified health professional.
How does numbness in the arms go away?
The answer to the question of how numbness in the arms goes away varies depending on the cause of the numbness. While arm numbness can sometimes be short-term and harmless, in some cases it is a symptom of a more serious disease. Therefore, attention should be paid to whether arm numbness is temporary or permanent.
If arm numbness is position-related, for example as a result of lying on the arm for a long time or standing still at a desk, it can be relieved in a short time with the following simple methods:
- Changing the position: It reduces the pressure on the arm and improves blood flow and nerve conduction.
- Doing arm exercises: Improves circulation and helps stimulate the nerves.
- Massage: A gentle massage can help relax the muscles and reduce arm numbness.
- Hot applications: Help relax the muscles, while cold applications can reduce swelling if there is inflammation.
- Rest: Arm numbness due to overuse may improve with rest.
However, in cases of arm numbness that recur frequently or do not go away, these applications alone are not enough. In this case, it is absolutely necessary to consult a doctor. It is important to determine the underlying cause and apply the correct treatment plan. Professional intervention is essential, especially in cases of nerve compression, vitamin deficiencies, spinal problems or systemic diseases.
The treatment process for chronic arm numbness usually includes the following steps:
- Physician evaluation and diagnostic tests (EMG, MRI, blood tests, etc.)
- Physical therapy programs and exercises
- Supportive vitamin and mineral supplements, especially vitamin B12
- Surgical interventions if necessary
- Lifestyle changes and ergonomic adjustments in the long term
For arm numbness to go away, it is important to focus not only on the symptom, but also on the underlying problem that is causing the symptom. If numbness persists, a specialist opinion should be sought.
