For the acute infections, I take a medrol pack (methylprednisolone), which immediately reduces the inflammation and allows drainage, and an antibiotic such as
levaquin, cipro, or whatever is appropriate
for the bug (culture is absolutely necessary). DO NOT let the ENT put you on antibiotic for anything less than 2 weeks. You need to be on them for a MONTH at least. Otherwise, you wind up not killing all the bugs, and they come back, more resistant to the antibiotic.
