How many of you have encountered it, what do you suspect caused it, and what did you have to do in dealing with it?
This is the first time I've encountered it on myself and I think it is the result of being too diligent in the correction of my posture in form work, trying for a deeper ma bo stance in ma bo stance training, trying for lower stances and slower movement in Tai Chi, and not mixing up my training routine enough. I train in Hung Gar by myself (up to 3 hours a day) and my sifu comes in for a few days every couple of months to load me down with forms. I end up practicing a lot of stuff in repetition with just a little variation during the week (been doing this for 2.6 years). I feel fine when I work out but then after I finish and cooled down for a bit, the muscle spasms and I get a deep pain in the butt. If I work out it's fine, if I sit, it's fine, if I squat it's fine, but if I stand in a static position.... that's when it really hurts.
I'm a PT but, unlike the other PT that frequents this forum, I work with people who are severely developmentally disabled in an ICF facility and I don't treat the general population with exercise related injuries. So the information is not fresh with me on a daily basis- I treat myself, I'm my own PT. I'm well versed on core strengthening, stretching and all preventive measures and I practice them but this particular problem has never surfaced in my 25+ years of exercising - even when I use to run 40 miles a week on top of everything. I've had low back pain that I got under control, proximal hamstring tendonitis on the same side as this piriformis problem that I got under control, but never have had a piriformis problems before. It palpates hypertonic and it's attachment at the sacral end is very tender to the touch.
What has been your experience with this in your martial arts training and what did you do to get rid of it? And oh, because I know I'll be asked, no, my iliotibial band is not too tight and I have good hamstring flexibility to that side. Currently, low back feels wonderful.... good for an active 51 year old man.
