There are many causes of shoulder and arm pain, including physiological causes and pathological causes, the latter such as cervical spondylosis, frozen shoulder, etc., and its treatment includes general treatment, medication, physiotherapy, surgery and so on. 1. Physiological causes: If the muscle pain is caused by exertion, you can choose to apply local hot compresses, reduce the activities of shoulder and arm, pay attention to rest, and generally can be relieved after sufficient rest. 2. Cervical spondylosis: when the cervical disc herniation compresses the nerve root, it can cause shoulder and arm pain. In this case, cervical traction can reduce the compression and relieve the pain to a certain extent. Non-steroidal anti-inflammatory drugs, such as celecoxib and meloxicam, as well as dehydrating drugs such as mannitol, can also be used to alleviate the edema of the nerve root, and drugs that nourish the nerves, such as vitamin B12 and methylcobalamin, can be used as well. When conservative treatment is ineffective, it is necessary to consider surgical treatment to remove the intervertebral disc and relieve the compression. 3. Frozen shoulder: When the pain is obvious, non-steroidal anti-inflammatory drugs can be taken orally, such as diclofenac sodium, loxoprofen sodium, etc. In serious cases, local closed treatment can also be taken. Physiotherapy such as massage and tuina can also be used. When the effect of conservative treatment is not good or the joint adhesion is heavy, surgical loosening treatment should be considered. The above medications should be used under the guidance of a doctor. When the pain in both shoulders and arms can not be relieved or worsened by resting, you should consult a doctor in time to clarify the cause of the disease and then carry out targeted treatment.
