About the Symptom
Arm numbness is best described as a loss of sensation or feeling in the arm anywhere between the shoulder and the hand. It can sometimes be described as a "tingling" or "pins and needles" sensation.
When to See a Doctor
Seek professional care if you experience any of the following symptoms
- Numb arm
Possible Causes
Generally, Arm numbness can be related to:
- Thoracic Outlet Syndrome
Compression of nerves and/or blood vessels at the base of the neck, causing symptoms like arm numbness. Symptoms worsen or occur when arms are raised, as this action increases pressure in the base of the neck. Causes include tumors, increased muscle or fat in the region, and abnormal ribs at the top of the ribcage.
- Cervical Spondylosis
A condition in which the neck bones (cervical spine) become damaged due to wear and tear. Risk factors include long periods of desk work and driving, previous neck injuries, and aging.
- Chronic Inflammatory Demyelinating Polyneuropathy
Chronic inflammatory demyelinating polyneuropathy (CIDP) or chronic relapsing polyneuropathy happens when the immune system attacks the myelin sheaths (protective fatty coverings) around the nerves. The exact triggers are unclear but could be systemic conditions like liver disease, diabetes, infections, cancer, immune system disorders, etc.
- Spinal Cord Intramedullary Tumor
- Multiple Sclerosis (MS)
- Syringomyelia
- Neuropathic Pain
- Spasticity
- Rheumatoid Arthritis (RA)
Related Serious Diseases
Sometimes, Arm numbness may be related to these serious diseases:
- Cerebral Infarction
Cerebral infarction refers to damage to brain tissue resulting from a stroke. It occurs due to decreased blood supply and oxygen delivery to the brain, causing brain cell death and brain damage. It is typically caused by a blood clot or fatty/cholesterol plaques blocking a blood vessel to the brain, but can also occur if a blood vessel ruptures and bleeds into the brain.
Doctor's Diagnostic Questions
Your doctor may ask these questions to check for this symptom:
- Do you have numbness or tingling in your arms?
- Do you have numbness in your arm?
- Do you have numbness from shoulder to elbow?
- Did you compress your nerve(s) by sleeping in a specific position?
- Do you have neck numbness when bending?
