hi, was wondering if anyone else has experienced this or has heard of it? for the past couple of week when i lie down i get a sharp pain at the top of my leg that spreads over my right bum cheek. sometimes i feel like i have ceased up and i cant move it! i can feel it in the day if i have sat at my desk too much or walked too much but at night it is unbearable. i have to get out of bed and walk around. do you know what it is and should i go to the doc or will it go on its own? thanks all xxxxxxxx
