My boyfriend, who is 21, has a chronic cough accompanied by a very thick mucous. This morning he coughed up a large amount of mucous with a little blood in it. The sputum was thick and looked like a giant glob of petroleum jelly - he says that this is normal, but my mucous is not so thick and gel-like. He has been smoking since he was 13 and I am worried about him. Any help is appreciated! Thanks!
