Cervical spondylosis causes arm swelling and pain.

Arm swelling and pain may be caused by cervical spondylosis. Cervical spondylosis can lead to excessive compression of neck and shoulder muscles, resulting in muscle spasms that pull on the arm and cause pain. For severe pain, medications such as Celebrex can be taken according to medical advice to relieve pain and inflammation. Additionally, blood-activating and stasis-resolving medications like Yaotongning capsules can be used to treat cervical spondylosis. It's also important to maintain proper posture and protect the cervical spine in daily life.
