Hi, I am new and just wondering if anyone is having lasting side effects from Chantix? I have awful joint and muscle pain, burning of my feet, legs and hands, stiff neck, and of course weakness. I have seen many dr.'s and all my tests are good. A brain mri showed some white spots but I was told it was nothing to worry about. I will know more when they send me the report and I can read it myself. They mentioned ms then changed their minds, neurologist and rheumatologist. I have had these side effects since 9/07, 6 days after starting Chantix. Anyone know how to stop this pain?
