I've had chronic hamstring issues for years and got passed around doc to doc and finally landed in a top sports med doctor who said he saw my type of situation all the time. Finally after years of docs saying we have no idea... basically the gist of it was he thought my back was likely pinching nerves in various spots causing the hammies to take the brunt of the pain. He said the only thing that'll make a difference is IMS or dry needling. I'm going for my first treatment next week. The doc said he recommends this to all his high end athletes and pro clients just for maintenance as well as when medically necessary, just found it strange I'd never heard of it. I've done accupuncture which is supposedly the hippy dippy version of it and got nothing out of that but I have done tons of physio (art, graston etc) /massage/chiros you name it, ive done it and nobody has mentioned this to me and I haven't found one person offline thats had it... so Im just curious to hear if anybody has had this done on them, what did you have worked on, did it make a significant difference, how was the process that sort of stuff.
