Al, for your description of the accident I'm afraid you may have some serious ligaments damage, even the meniscus, but the first thing is just having simple Rx to discard bone fractures. Once inflammation goes down, they'll see, probably a RMI scan is needed to have a complete diagnosis, though that's not the most important. Many times RMI can't give as much information as an arthroscopic procedure. I wish you don't need that By now just take your pills, rest and try to enjoy your music. Keep us posted and get well.
