I have had TMJ for a long time but am undergoing treatment with braces. It has improved a lot but recently I started lifting weights again and I am noticing that I am getting a lot of lactic acid buildup in my jaw which is also causing tension. I am not going to stop lifting weights as its an important part of my life and something I need to do so I am wondering if anyone has any suggestions on what to do about the lactic acid buildup and release the tension.

I am going to see if I can start to take flexeril again, I took it a while ago but stopped since my teeth were so misaligned back then it was basically pointless. Any other advice is appreciated.
