I'm trying to figure out what this pain issue of mine might be. The location is along the horizontal crease between the bottom of my buttocks and the top of my hamstring. It activates when I sit, and gets worse the longer I sit. If I sit long enough, it gets so bad I can't sit anymore (e.g. sometimes after 1 hour or less). The pain is burning and aching.
I also suffer from coccydynia, although this emerged later than that. I believe it started when I was sitting on a chair that was too high for my leg length. Later it reemerged when I was stuck sitting in a very hard wood chair.
I've read about conditions including ischial tuberosity, piriformis syndrome, hamstring tendonitis, bursitis, and sciatica, but I can't find one that describes this particular pain pattern.
Thanks for any help!
