I play football, climb and workout regularly. Well I used to. Around 3 months ago i had knee pain that had come on gradually in the back of centre of my knee, it would cramp up whenever bending it back or squatting, and If i sat or lied for a prolonged period of time it would also feel like it was cramping up in the back.
I decided to climb anyway and had the sensation that I had pulled my hamstring, so i stopped immediatly.
Ever since I have been experiancing this cramp behind my knee when resting or crouching / pulling leg back. It has been 2 and a half months since I last attempted any sport, I have been doing hamstring stretchs as recommended by a physio, but they do not seem to have helped.
Can anyone give me any idea's what the likely provlem is?
