I have had this pain for about 1 to 2 years now but it started really hurting last year and continued to present. I have got a sharp sudden pain in my bum/thigh, I had it in both legs but for some strange reason it stopped in my right leg which is my weakest leg because i have always been stronger on my left leg. 

I currently play rugby and have had the physio's rub my thigh and bum but it hasn't changed :( It hurts when i walk,jog and run (sprint) i have pain when i getting of the chair or floor. I have tried loads of different stretches but i haven't found one that works. I have been told by a couple of rugby team mates i have short/small hamstrings in my leg.

I would like some help because it is killing me and not helping me preform in games while playing rugby.
