Hand numbness and arm swelling or pain can be caused by various factors, commonly including:
1. Nerve compression: Cervical spondylosis is one of the most common causes. Degenerative changes or herniated discs in the cervical spine may compress the nerve roots, leading to arm numbness and pain.
2. Periarthritis of the shoulder (frozen shoulder): This is a chronic inflammatory condition primarily affecting the tendons, bursae, and soft tissues around the shoulder joint. It may cause muscle tension, adhesion, and stiffness, resulting in arm swelling and pain, with symptoms sometimes radiating to the fingers.
3. Circulatory problems: Maintaining the same posture for prolonged periods, such as sleeping with the arm compressed or sitting immobile for long durations, may impair blood circulation and cause arm numbness and swelling.
4. Diabetic peripheral neuropathy: Long-term high blood sugar levels can cause nerve damage, leading to symptoms such as numbness and tingling in the hands and feet. If the condition progresses, it may also affect motor function.
5. Carpal tunnel syndrome: This condition is caused by compression of the median nerve within the carpal tunnel and commonly presents as hand numbness and pain in the anterior wrist.
If symptoms persist or significantly affect daily life, it is recommended to seek medical treatment immediately.
