I'm a registered nurse and one of my jobs is at an acute care rehab. You need PT and rest. The tear will probably heal on its own as long as the tendons/ligaments aren't torn. if they are you LIKELY need surgery and you should seek the opinion of at LEAST 2 more doctors. find a doctor you like, come up with a plan with him and follow it. Medicine is called a "practice" for a reason, it isn't a true science as people think. Medicine uses science as a tool, but 90% of medicine is trial and error, you just need to commit to healing yourself and put sterioids and lifting out of your head until you can fix your body.
