About a month ago i injured my knee causing me not to walk. I went to the ER and they found no breaks gave me crutches and a brace and sent me home. I can kind of walk now but not with my leg straight. When i try and straighten my leg the top of my knee feels like its going to break (by ny thigh kind of) Does anybody know or have had similar problems that were fixed? I would really appreciate if someone told me.thank you.
