I have also had the Botox injections done. I had my first series done, with no results, unfortunately. Since having them done, I have had more problems with body aches and pains. I don't know if this is caused from the Botox injections or not, but my neurologist said that it was possible. I have decided not to go back for any more sessions.
I was told by my neurologist, who has the most experience of anyone in the U.S. doing these injections for headaches, that the second time was more successful than the first, and the third more successful than the second, and also the effects last longer w/ each session. The injections have about a 90% success rate, with a lot of patients being able to come off of meds completely. Unfortunately, they are pretty expensive to have done, and some insurance companies won't cover the charge. The injections that I had done were in my forehead, down my neck, into my shoulders, and then down my back. As I said above, it didn't seem to do anything for me, but of course I have a high tolerance for meds, so that has been my major problem. Just wanted to add a little more info to what had been given. If these injections work for you, then it sounds like a wonder drug. I know that is what I was hoping for.
Hugs,
