In daily life, if a patient has arm pain after a day’s work, the reason is that the activity is high, resulting in damage to the soft tissues of the arm muscles, producing excessive lactic acid accumulation and soreness. In this case, first of all, the patient should stop the activity and rest in bed, while elevating the affected limb. For the arm area, physiotherapy apparatus can be baked or topical ointment can be applied to activate blood circulation and remove blood stasis, and traditional Chinese medicine massage or Chinese medicine meridian treatment can also be used. Local physiotherapy such as acupuncture and herbal iontophoresis can be performed to improve local blood circulation. If the patient feels heavy soreness, he can also take oral non-steroidal anti-inflammatory drugs, and can take oral celecoxib to relieve local pain. All in all, after this condition occurs, the patient had better go to the hospital in time, after the doctor gives a clear diagnosis and then take the correct symptomatic treatment, only then the symptoms will be gradually relieved.
