oral thrush
"I think that it has turned my lips black,  unless there's something else wrong. I don't know. I love the medication. It really works and right away. My mouth, throat, and chest stopped hurting after taking it twice. I have coughed up blood before I started this medication. My cough is better also. I just can't figure out why my lips are black. I go to the doctor this week for a biopsy,  so, I'll show the doctor."
