Sinusitis
"First of all To the people saying biaxin should be off the market, You do realize that there are different kinds of antibiotics and what works for uou wont work for me , and vice versa. For example I am allergic to penicillin and any antibiotic related to it makes me feel awful and worse. But it works for many other people. That being said Biaxin WORKS for me. In fact It instantly worked by the next day when I woke up my nose didnt have green chunks in it anymore.  Yes it gives metallic taste. Yes day 3 I have head ache behind my eyes. ( maybe the medication working on the more deeper infected area). If you get a dull headache Take an advil dont stop taking the medication... A migraine I would stop but a mild headache I think is Managable."
