Numbness in the arm can arise from various factors, ranging from simple posture-related issues to underlying medical conditions. This article aims to shed light on the common causes of arm numbness and provide answers to some frequently asked questions.

Causes of Arm Numbness:
1. Poor posture: Maintaining an incorrect posture for extended periods can compress nerves and lead to arm numbness.
2. Pinched nerve: Nerves can become compressed or pinched due to injuries, herniated discs, or conditions like carpal tunnel syndrome.
3. Thoracic outlet syndrome: This occurs when nerves and blood vessels in the shoulder area become compressed, causing numbness and tingling in the arm.
