I'm considering traptox to help with chronic headaches, which I'm also treating with a neuro. I carry a lot of tension in my traps and other remedies haven't helped much (e.g. massage, chiro, accupuncture). Any tips on how to find an experienced provider? Also, I saw someone else post about the same procedure and multiple people responded that $900 was very expensive. The providers I've located so far are asking much more than that. What is a reasonable price window?
