Sciatic nerve pain behind the knee
Hi, I've had a pain at the back of the knee, just where it folds when bending. I'm into running, triathlon and cycling and have had the pain for about 8 months. Basically if I do any type of excerise it flares up with a bit of swelling behind the knee. I've had an MRI, Ultra sound and X-ray and all have come back clear. Physio and specialist say it may be a tight or inflammed sciatic nerve, but they can not be sure. I'm 34 and at the time of injury I was about 200lbs, it became sore while running.
I've do a stretch were I sit on a table, put chin on chest and raise the left leg straightening at the knee. Left (sore) leg can not stretch as far as the right. Also when the left leg is straightened and the toes pointed back again it does not have the range of motion as the right (good) leg.
It tends to be tender sore first thing in the morning but will subside after 15-20mins once it has "warmed-up". Then if I do any type of excerise like 10mins on bike it gets sore about an hour or two after finishing. I can do weights on it with no pain. Basically if I don't do anything I can cope with it but with any type of excerise it gets pretty sore.
Can anyone help please.
