My boyfriend stopped smoking cold turkey a few weeks ago and he said that this last week he's been coughing up a black stringy stuff and sometimes there are red specks in it, probably blood. He said he thinks he had bronchitis last week. He's been having really bad hot flashes and sweats like crazy when he does. He's worried because he doesn't think that it's from him stopping smoking, he says his body hurts. Is it just some serious side-effects of quitting smoking or could it possibly be something else like an infection or pneumonia or something? Please help. He doesn't have the money at the moment to go to the doctor's to find out, so I'm trying to research.
