I am in a similar situation. I tried it once with short-term relief...maximum 8 weeks.
I was going to try again to see if the pain relief could be reproduced.

For those of you with experience in this area -- if Botox works for you, can you just keeping getting it a few times a year for the rest of your life??

I've been told different things. One doc said you can/should only get Botox 2 or 3 times total. And, then another doc said you can continue to get Botox as long as it works for you (but should space the shots 4 months apart).

Would really appreciate any info.....
