Why do your arm get a numb feeling?

A numb feeling in the arm can occur due to various reasons, such as nerve compression or irritation, often from sleeping in an awkward position or repetitive movements. Conditions like carpal tunnel syndrome, herniated discs, or peripheral neuropathy can also lead to numbness. Reduced blood flow due to circulatory issues may contribute as well. If numbness persists or is accompanied by other symptoms, it's advisable to seek medical attention.
