Causes of Arm Numbness
Arm numbness can be caused by a variety of factors, including:
Temporary Causes:
- Compression: Sitting or lying in the same position for too long can compress nerves and restrict blood flow.
- Poor circulation: Conditions like Raynaud's disease or peripheral vascular disease can reduce blood flow to the arms, causing numbness.
- Injury: Trauma to the arm or neck can damage nerves and lead to numbness.
Underlying Medical Conditions:
-
Compression of nerves or blood vessels in the space between the collarbone and first rib.
-
A blockage or rupture in a blood vessel in the brain can cause numbness in the arm, among other symptoms.
-
High blood sugar levels can damage nerves, leading to numbness and tingling.
-
An autoimmune disease that affects the central nervous system, including nerves in the arms.
-
Compression of the median nerve in the wrist.
Other Factors:
- Medications: Some medications, such as chemotherapy drugs, can cause numbness as a side effect.
- Vitamin deficiencies: Deficiencies in vitamins B1, B6, and B12 can contribute to nerve damage.
- Alcohol abuse: Excessive alcohol consumption can damage nerves and cause numbness.
