I've quit smoking I'm on day 17 cold turkey. I'm suffering with real tight chest and hard breaking I've been to the doctors and my lungs are clear and nothing wrong with my chest neither. Ever since quitting I've been having chest pains had chest pains when I was smoking but not as bad as this now. I do suffer from anixety which is also bad. But I'm wondering has anyone else had this tight chest and chest pains after quitting smoking?
