Pain when lifting the arm after a fall may be caused by ligament injury, shoulder dislocation, humerus fracture and other conditions, which need to be treated with medication and surgery according to the cause of the disease. 1. Ligament injury: Usually, patients need to follow the doctor’s instructions to use ibuprofen, acetaminophen and other analgesic treatment, so as to relieve the symptoms. Minimally invasive arthroscopic surgery can also be chosen according to the degree of the disease, and some patients can also take microscopic treatment. 2. Shoulder dislocation: Usually, patients can use non-steroidal anti-inflammatory drugs such as diclofenac sodium, indomethacin and other non-steroidal anti-inflammatory drugs as prescribed by the doctor, and some patients can also use opioid central analgesics such as tramadol and codeine. At the same time, manipulation or incision can also be performed under the guidance of the doctor, and if necessary, joint capsule overlap suture, biceps long head tendon suspension, etc. can also be chosen to carry out. 3. Humerus fracture: Usually, patients need to undergo manipulation first, and if necessary, can undergo incision and internal fixation. Postoperative antibiotics such as cefuroxime and cefoxitin should be used under the guidance of the doctor. It is recommended that when the symptoms of pain occur when the arm is lifted after a fall, consult a doctor in a timely manner to clarify the cause of the disease and cooperate with the doctor to carry out targeted treatment.
