Why do you get ulcers in your mouth after you quit smoking? -
Often times when you quit ingesting poisonous substances, for a time afterwords, your body forces these poisons out. creating sores, boils, and the like. it may take a while, but drink lots of water to help, and maybe consider a toxin flush. eventualy, it will subside. Congrats!
No, that does not sound normal. You should see a DR.
