I have posted about this before but am happy to chime in. I did 12 or 13 shock wave sessions last winter at a chiropractic/PT office along with some other therapies. Unfortunately I did not notice an appreciable difference. I also have a red light unit that I use at night for an hour which seems to alleviate some tingling at night. It is hard to say for sure but I notice when I stopped the red light over the summer my symptoms came back in full force.
