I posted a while back looking for help with Hairy Tongue. Several more months have passed and I still have hairy tongue. It started almost a year ago when I took a 1 week course of Metronodizole (Flagyl). The antibiotic did its job but caused this condition called hairy tongue as a side effect that seems permanent. My tongue looks like it has a white coating of thousands of little elongate papillae. Almost like my once healthy pink tonge now has a 1970's shag-carpet growing on it.
