For several months now I've been having some discomfort at the top of my leg, just underneath my right buttock, on longer runs. In the 6 weeks or so, I've had more time available to train so have been running and cycling more. Due to that I find that the discomfort comes on much quicker and sometimes just walking on the flat give me grief. It's stopped me running at all this last week. Also I find that the pain leads to a tightness in my lower back. I've already been to see a physio but it's not helped. I've looked into it a bit online and it seems to me to be piriformis syndrome but I'm not able to say for sure. Has anyone had any similar issues and does anyone have any suggestions as to how I can manage it?
