I have been bothered lately by muscle spasms in my neck up from my left clavicle where I had 5 surgeries the 4th resulted in a staph infection from the operating room. Last week, my pain medicine physician gave me an injection in my left clavicle to help with those tight muscles from all the scar tissue. The injection did help but I still have some problems cause I'm trying to go down on the Kadian dosage cause it makes me so tired in the daytime. I was injured at work in 1990, almost 20 years ago! Does anyone else have this problem? Thanks for your ideas! Happy Holidays to all!
