With a shoulder sprain, it takes about four weeks to recover, but only if proper treatment has been done. Shoulder sprains are often accompanied by damage to the shoulder capsule, ligaments around the shoulder joint, and bone, so before treating such patients, it is important to first conduct a thorough evaluation to clarify the specific location and severity of the injury, and then do targeted treatment. In the case of minor damage to the joint capsule and surrounding ligaments, conservative treatment can be chosen, requiring the patient to take strict braking and rest, and to use anti-inflammatory, anti-swelling, and pain-relieving medications to treat the injury. If the doctor deems it necessary, the patient’s shoulder joint will also be immobilized using a shoulder harness or other means. If the patient has serious ligament damage around the shoulder joint, such as a tear or avulsion fracture of the rotator cuff, surgical treatment is necessary. After the above treatment, the patient should also do the corresponding functional exercises under the guidance of the doctor, so as to ensure a better recovery of the injured shoulder joint.
