Its not possible to have a MS relapse after smoking; however its beeen proven that once you stop smoking, your body goes thru so many (positive) changes that you are going to have some issues. Coughing, sore throat, head aches, even flu like symtoms can present, these are usually short term.
You may FEEL like you are having a relapse, but youre probably not. And, if you are, its not due to stopping smoking. Its due to the chemicals in your body coming out. Congratulations if you actually managed to stop! Youre going to go thru a period of feeling worse prior to feeling better; but STICK WITH IT! ITs the best long term thing you can do for your body!
