After experiencing small tremours on the opposite side of my face to my TN side I sent off to an internet bookstore for a self-help book on TMJ. I reasoned that it might help as I have neck & shoulder discomfort, whistling in my ear, pain in my forearm and a history of teeth grinding and jaw clenching. The TN started after two severe attacks of back pain with regular muscle spasms.
Anyway, the book arrived a week ago. I instinctivrly feel it's right for me as it takes a holistic approach, treating the body as a whole interconnected system. There are exercises to strengthen and relax the jaw, as well as exercises to re-align the whole body. My head/neck posture is poor [particularly at the computer] and it addresses this. The jaw relaxation position [lips closed, lower jaw relaxed, tongue on the roof of the mouth away from the teeth] has been so useful.
It's not a quick fix. This will take a lot of time; checking & relaxing tight muscles, doing the exercises and learning new patterns to replace bad habits. Last night was not a good night. My jaw still hurts and often it winds up towards a nerve attack but I try the relaxation exercise or use a warm face-cloth and it goes away. Since I got the book I've not had a nerve shock. It could all go wrong tomorrow but at the moment I'm not on any medication at all.
I think the main thing it has given me is the feeling that I'm partly in control of things instead of a victim of pain. My life no longer feels as if it shrinking and I've become aware of how tense and stressed I was, creating yet more body tension.
I'll report how it all goes but would welcome feedback from people who may have tried something similar.
