I’ve had an extremely tight jaw that I grind heavily at night with a nightguard since I was about 10 years old. PhD. Win did acupuncture on the back of my neck, head, and jaw, over the course of 4 appointments ( I would have gone to many more, but it was time for me to return to Australia). My jaw has opened up and relaxed continuously since then, mixed with a fair bit of self massage. The Acupuncture helped to open up and bring deep, very old knots to the surface, where I could then open them further through massage. If you suffer from TMJ and grinding, I can’t recommend PhD. Win highly enough- he gets into the issues that are causing it to begin with. Thank you PhD.. Win!
