I've had a cold and cough for the past two weeksno fever or anything else. My cough started off dry and turned into a wet cough about a week ago. I initially took Azithromycin 500 once a day for five days, and now I'm on my third day of taking Cefixime 200 twice a day. I've also been taking Rexcof DX cough syrup three times daily. The cough is getting better, but for the last two mornings, I've noticed blood in my sputum. When I wake up, I have this urge to cough and it brings up sticky mucus with red color, but it only happens in the morning. The wet cough is still hanging around, but it's not as bad as before. Could you help me figure out why there's blood in my sputum?
