Why Your Arm Hurts

Muscle strain:

- Repetitive motions, such as typing, can strain the muscles in your arm, leading to pain.

- Overuse of the arm during activities like sports or manual labor can also cause muscle strains.

Tendonitis:

- Inflammation of the tendons, which are the tissues that connect muscles to bones, can cause arm pain.

- Tendonitis is often caused by overuse of a particular muscle or tendon, such as the biceps tendon in the elbow.

Carpal tunnel syndrome:

- Compression of the median nerve in the wrist, which can lead to pain, numbness, and tingling in the hand and arm

Nerve damage:

- Damage to the nerves in the arm, such as the radial or ulnar nerve, can cause pain, numbness, and weakness in the arm and hand.

- Nerve damage can be caused by trauma, such as a fall or car accident, or by other medical conditions, such as diabetes or arthritis

Arthritis:

- Inflammation of the joints in the arm, such as the shoulder, elbow, or wrist, can cause pain and stiffness.

- Arthritis can be caused by wear and tear, aging, or other medical conditions.

Broken bone:
