Upper arm pain in the right arm may be caused by physiological factors such as lactic acid buildup due to overwork or muscle pulling injury, or it may be caused by frozen shoulder, rotator cuff injury, cervical spondylosis and other causes.
1. Physiological factors: If lactic acid buildup or muscle pulling injury is caused by overwork, the pain can be relieved or disappear after resting for a period of time, and no special treatment is needed.
2. Frozen shoulder: Frozen shoulder can cause pain in the upper arm, accompanied by limited movement of the shoulder joint in all directions, usually occurring at the age of about 50 years old, and the pain is obvious at night.
3. Rotator cuff injury: usually there is a history of trauma to the shoulder joint or degenerative changes in the soft tissues of the shoulder joint, which can be clearly diagnosed by MRI.
4. Cervical spondylosis: Cervical spondylosis compresses the nerve roots innervating the right upper limb, which will cause pain in the right upper arm, accompanied by numbness and discomfort in the right upper limb and neck pain and discomfort, etc. It can be clearly diagnosed by cervical spine MRI.
There are many other causes of right arm pain, such as trauma, myofasciitis, etc. If the right arm pain is not relieved after resting, or recurring or even aggravated, and the pain is aggravated at night, you need to go to the hospital in a timely manner, improve the examination to clarify the cause of the disease, and comply with the doctor’s instructions for treatment, so as to avoid delaying the condition.
