Avoiding activities that cause pain, applying ice packs to the shoulder periodically and taking nonsteroidal anti-inflammatory medications are the initial recommended treatments for shoulder tendonitis, according to Healthline. If symptoms fail to resolve, physical therapy, steroid injections and surgery are other treatment options.
Individuals suffering from shoulder tendonitis can limit pain from the condition by maintaining proper posture, taking periodic breaks from repetitious activities, avoiding carrying heavy bags on the affected shoulder, avoiding sleeping on one side each night and avoiding repetitive overhead arm lifts, advises Healthline. Stretching the shoulder while taking a hot shower may also be beneficial, notes Cleveland Clinic.
A person under the age of 30 who experiences shoulder tendonitis for the first time and immediately follows the proper treatment can expect to recover within two to four weeks, according to Cleveland Clinic. Older patients and those experiencing repeated episodes of shoulder tendonitis may find that they require months to heal. In some cases, surgery may be necessary to repair a muscle or tendon or to prevent further fraying of a muscle or tendon. Patients must begin a rehabilitation program within a day or two after surgery to restore strength and normal range of motion to the affected shoulder.
