I had botox done to neck, shoulder blade area and a little on forearm. 3 times now. Each time, it took about a week to feel relief. (It just freezes the spasming by the toxin in it.) It lasts about 3 months - but that's with the best time at 1 1/2 month - because it comes on slowly and goes off even slower.

I noticed after botox came on (you'll notice relief) that then I felt the other areas / muscles that were so painful - so it was very helpful and I'd do it again, but it just relieved my pain about 30 * to specific areas injected.

Injections are nothing - at their worst they are a quick bee sting - my doc and I used to yodle to get through them like a joke...just because I was nervous.

warning - no one knows yet what the long term use of botox does in the body. It is a toxin. It is only effective for about 6 times, then the body does not respond. WhY? One must ask...
