The symptoms of soreness in the arm: 1. may be caused by excessive physical work, muscle strain or heavy lifting; 2. may also be caused by cervical spondylosis and other nerve compression, resulting in pain and discomfort in the arm; 3. may also be caused by local lesions, such as local soft tissue injury, local soft tissue tumor or osteoma. Therefore, when the symptoms of arm pain appear, first of all, avoid strenuous activities, avoid lifting heavy objects, rest in bed, elevate the affected limb, give appropriate topical medication to relieve the symptoms of pain and soreness, and use blood-stasis-boosting medication for supplementary treatment. If the symptoms are relieved significantly within a short period of time, the problem is generally not serious. If there is no change in the symptoms of arm soreness after topical medication and physiotherapy, and the condition is progressively worsening, it is important to go to a regular hospital in a timely manner to avoid delaying the condition.
