Hi. I'm new to this Forum. I'm a (mediocre) fell runner and live in the Lake District. I found this site whilst searching for help on a (probable) piriformis problem. It started after I fell heavily on my rear end whilst walking in the Alps last September (07). It comes and goes, and has so far resisted countless sessions of physio (from a sports physio specialist who has helped successfully with numerous other injuries) and sports massage. Oh, and 3 sessions of acupuncture, including electric pulse treatment. My symptoms are similar to those injuries described by others on this site (esp geordiebezza): pain deep in the bum (right, accelerator pedal, side) that stretches down the back of the hams, sometimes as far as the tendon that goes to the back of the right knee (inside). I can jog up hill OK and cruise down hill without too much bother (being a fell runner, that's a relief!), and can keep going (slowly) for a couple of hours. But I can no longer do speed sessions or maintain high speeds on flattish runs (esp on roads). Driving is also a problem. Anything over an hour and it becomes very painful. Sitting at a desk isn't great either - depending on the seat design/position. Although I am still able to train and even race, I am becoming increasingly frustrated and depressed about this. So I'd welcome any thoughts on possible treatments other than those I've already had. (My physio does not think the problem stems from a trapped sciatic nerve in my spine.) Thanks. Quentin
