If you have injured your shoulder tendon, you should consult an orthopedic surgeon and take an MRI film of your shoulder to clarify the extent of the tendon injury, and then take symptomatic treatment. If the shoulder tendon is only partially injured, you can take conservative treatment by prohibiting activities, putting brakes on the shoulder, applying ointment to activate blood circulation and resolve blood stasis, or applying Fotarin spray, and using acupuncture, moxibustion, and Chinese herbal fumigation to activate blood circulation and resolve blood stasis, reduce swelling and pain, and taking oral bruising or blood activating drugs. If a complete rupture of the shoulder tendon is found after MRI examination, surgical treatment should be performed under anesthesia, with incision and tendon anastomosis, and postoperative shoulder braking and oral blood-boosting medications are also required.
