Fred;
RE; the value of HLSH, I've gone to a half dozen PT sites, some were OK, some good, and the one I went to last I insisted on one therapist. This guy is into soccer, golf and physical fitness and I think the women and young guys did not have the strength to get deep into the muscles.
Now don't laugh but my insurance will not allow 2 sessions in one year, so my Dr. sent me to accupuncture one year and it worked well (for back spasms). It did not take right away, but after a couple of weeks, it worked wonders, and the Dr. was into small caps.
