I just had botox injections yesterday in my upper back and I already can feel the difference. I developed myfascial pain syndrome about 14 years ago and had a spinal fusion on c-5 / c-6 in 1997.
I've been through trigger point injections, cervical epidurals and wear the durageis 25 mg patch.
My insurance would not cover it but it's worth not having that constant, nagging pain.
Yay!!
