re: Is there any legit science supporting dry needle physical therapy?

I did it on my right calf for a while due to muscle knots causing Achilles issues. I could physically feel with my hands that calf was more loose than the other after treating for a while. Was also doing ART and Graston scraping, so it wasnt just dry needling, but something was working. Had them work on both legs after that.

I only do it if I need it though. It isn't pleasant.
