I wish I tried it sooner. I suffer from chronic right TMJ joint pain for years resulting in constant pain at the TMJ joint, my jaw, temple, left side of the head extending to the neck. You can bet I've tried everything. Pain meds work but I don't want to rely on them. This little device is surprisingly effective to temporarily relieve the pain for several hours. It is small enough to fit in a pulse or a pocket, but gives out quite strong electrical impulse.

I got this acupressure pen with the point functions chart and the acupressure chart & I was able to help my daughter with a physical ailment that came up as a result of a *lot* of stress & it worked! Of course it didn't clear it up in one go (we just got it), but it was effective & the path is being cleared. The instructions that come with this kit are clear & easy to understand. I do need to say though that the roller head didn't do anything. A very good little product, especially for the price.
