ve been told it was a sprain, tendonitis, a torn meniscus, and shoulder shrugs. For me, a
patella knee brace and physical therapy and never running again (ugh) fixed it pretty much, But I was older and had a long history of heavy exercise, and you have the advantage of being young -- so be wary of being told you need surgery. If you are, get a second opinion, because if you're able to walk as well as you are you probably don't need it.
