It is recommended to go to the hospital for an X-ray examination of the arm to see if there is a fracture. If a fracture is ruled out and only a local soft tissue contusion is present, you can usually go out with Chinese herbal medicines that reduce swelling and pain, invigorate blood circulation and remove blood stasis, such as San Huang San or pain relief cream, which can reduce swelling and pain. In addition, pay attention to rest and avoid excessive activities, so that the local swelling and pain can be gradually relieved and the injured tissues can gradually recover, the pain can be slowly relieved. If the pain is severe, you can also take oral anti-inflammatory and pain-relieving drugs, such as ibuprofen and acetaminophen, or you can also take Yuanhu pain-relieving pills and other Chinese medicine to activate blood circulation and remove blood stasis, which also have good pain-relieving effects.
