Something else to add, If i lie flat on my front and raise my left leg it hurts and feels shakey. Like as if my leg is real heavy. If i tense my leg/buttock muscles and do it the pain is hardly there.
When walking and this is really hard for me to describe being non technical termed so apologies in advance. At the top of each thigh, if you prod about with your thumb and i mean right at the top where your leg bends there is something like a thin tendon / muscle (feels approx 1/2 - 1 cm width, seems to stop at the boney hip bit that sticks out and seems to travel vertically down my thigh). When relaxed, on my injured side that whatever it is feels much harder than the good side. If i put some pressure right on it when i walk it takes a lot of the pain away.
