Yes , pain in your muscles after using Nicotin patch is very common. you can have sharp excrutiating pain , or throbbing pain or it can be seen as a dull ache accompanied by the numbness of arm which you have used the patch. Quitting smoking is a very difficult task, but since you have decided to quit, please stick on to your decision and try to bear/ ignore the pain you are going thru. Try not thinking about smoking or pain, Try to be away from friends who smoke as it can trigger your tendency to smoke again. Indulge in certain hobby or activities, go for long walks, spend some time with your pet if u have any,or watch a movie as these can divert your mind from pain and tendency to start smoking again. Drink adequate water, and keep yourself hydrated. If severe pain persist please consult a physician. Hope this answer would help you Thank you
