Thank you Jon, I wasn't looking to treat the headache. I figured if the medicine the doctor was prescribing wasn't working it would be doubtful that Botox would. I thought that the injections might help with the jaw pain though.
Spiny - I am all about the research as I am a researcher myself. Placebo or not I will continue on. I won't try the injections with any one that isn't licensed or experienced. I was looking to see if anyone had any experience with the injections and the nerve pain relief in the jaw area. My teeth are so sensitive, chewing on anything, even gum is painful. Brushing my teeth hurts so if Botox would provide relief in that area I would be grateful. I won't do anything without first checking with the clinical trial.
All interesting things to consider. I think I might wait and see how the research study goes and if the jaw pain continues past that. I have no desire to be back on prednisone after being off of it for 18 years.
