Doctors Diagnosis

So i went to see a doctor today about my knee. i never see the same doctor every time i go which is annoying! so i told him i've had an injury since i was 16 and he looked at my notes and stuff and got to know a little about how it came about. after examination he said that one of the three ligaments holding my joint together is weak and the best way forward is physio. finally! i'm actually getting something done about it. i questioned as to what would happen in this didnt work and the next option will definitely be surgery. i feel okay about it because I know it will help me in the long run and my knee will finally be okay again. but thats not an option right now. im just waiting to get referred to the hospital and start my physio. so im happy i got some proper advice and i can now get on the mend!
