I've had tmj from clenching for about two years. At first I got Botox in the masseter muscles which completely eliminated all pain. After a year I went back and got it again but this time it only lasted 6 months. I got it two weeks ago but this time it hasn't worked. The doctor won't give me a top up as she has said the masseter muscles aren't enlarged so it would risk damaging the muscles in the face. I know I'm clenching but can't stop. I have a real tight painful jaw as well as neck pain and pain around the ears. Has anybody managed to treat this successfully without Botox?
