I'd say I have fairly tight ITBs but I have no pain with obers testing. I have seen a physio about the issue and they are a little baffled as to what is causing the problem. My gut feeling is that it is coming from the short head of biceps femoris but the sports physician said it was unlikely the nerve would get entrapped here. I have had some massage to the hamstring but it is just so difficult for anyone to get into. The restriction feels very deep. I am having an ultrasound of the nerve on monday. Hopefully something will come of that.
