Causes And Symptoms Of Arm Numbness


Arm numbness in one (unilateral) or both (bilateral) arms is an uncommon condition in which you experience a lack of sensation. Over the length of the arm and into the hands and fingers, the sensation can extend.

Arm numbness normally results from a lack of blood flow to an area or damage to the nerves. Infection, inflammation, trauma, malignancy, and other abnormal processes may also result in arm numbness. Most cases of arm numbness are not due to a life-threatening disease.

Arm numbness is often associated or followed by paresthesia called pain-like pins-and-needles, prickling, or burning sensations.
