Badminton strain on the shoulder usually causes injury to the muscles and soft tissues of the shoulder joint, such as the supraspinatus, infraspinatus, teres minor and teres major muscles, etc. After the injury, local bleeding and exudation can cause painful symptoms. It is best to immobilize the shoulder joint with a brace, suspend the upper limb on the affected side, apply heat and physiotherapy, or apply Chinese herbal medicines that have the effect of activating blood circulation and removing blood stasis, such as safflower oil or orthopedic water. Of course, you can also take some oral medications that have the effect of activating blood circulation and removing blood stasis, such as Qin Chuan Tong Pao tablets, which can effectively improve the blood circulation of the strained area, thus facilitating the repair of soft tissues. If the pain is obvious, you can take oral non-steroidal anti-inflammatory and pain-relieving drugs, such as Fenbid, Furtalin tablets or Cilabao capsules, etc. These drugs can effectively reduce local sterile inflammation, which can achieve the therapeutic effect of reducing pain. For patients with more severe symptoms or those who do not achieve good results with the above conservative treatments, arthroscopic surgery can be performed to repair the muscle and soft tissue damage.
