Lame excuse

I hurt my left knee biking a month ago. It is still bothering me and has limited my activities this past month...that kills me because I am missing out on a lot of summer stuff. I saw a doctor already and a physical therapist. They think it is my meniscus. I wonder if it is a small tear or I really messed it up. Problem with the meniscus is only its outer parts are reached by blood flow so it wont heal on it's own if the tear is big enough...in that case, surgery is the only real option to get the knee working 100% again.
