Arm pain, usually associated with soft tissue damage, osteoarthritis, joint dislocation and other factors, should be combined with the cause of the general treatment, drug therapy, conservative treatment or surgical treatment. 1. Damaged soft tissues: related to chronic strain, need to pay attention to rest, and reduce the amount of activity, reduce the local burden. When the pain is severe, hot compresses can be applied to accelerate blood circulation, and if necessary, microwave physiotherapy, infrared physiotherapy, etc. Non-steroidal anti-inflammatory painkillers, such as ibuprofen, etc., can be taken for treatment. 2. Osteoarthritis: Osteoarthritis pain is more serious in the early stage, patients can follow the doctor’s instructions to take oral non-steroidal anti-inflammatory drugs, such as ibuprofen, celecoxib and so on. If the symptoms are serious and the effect of oral drugs is not good, we can consider intra-articular injection of betamethasone and sodium vitrate. 3. Joint dislocation: If the joint dislocation causes arm pain, it is necessary to carry out manipulation and immobilization treatment, including brace immobilization and plaster immobilization. If the effect of fixation is not good, surgery can be considered for internal fixation treatment, together with infrared physiotherapy and acoustic physiotherapy. Avoid lifting heavy objects when you have arm pain, otherwise it will aggravate the condition. If the condition does not get better, it is necessary to consult a doctor in time and make diagnosis and analysis by X-ray and magnetic resonance examination.
