The physiotherapist I see for the IMS was trained by Chan Gunn. So most likely taught with a short clinical course to certification. Not ideal but he's helped so far. I think in my case, I had severe spasms which added to the amount of discomfort post treatment. In conjunction, I've always been very contact sensitive. I can literally feel a mosquito needle going into my skin. So the entry points in my lower back will tingle for a few minutes afterwards.
