White/yellow coating on tongue - Not thrush
Hi all, I was hoping to get some insight on a problem I've had for the past 8 months. Here's how it started:
I started having a dull, persistent abdominal ache. My friend (who's an MD) told me to try taking Zantac for a couple weeks to see if that would help. On the 3rd day of taking it, I woke up with this yellowish coating on my tongue - mostly in the back - and bad breath. I'm not sure if the Zantac caused this, or it was just a coincidence that it happened at the same time.
Ever since then, this coating has persisted. It's the worst when I have come home after work and haven't eaten/drank much that day. At that time, I can literally scrape my tongue and a bunch of it will come off -it's really thick.
At other times, it's not as bad - always worse in the morning. I can brush 80-90% of it off with a toothbrush but it always comes back the next day. I also have a really dry throat now. I have no other sores or coating on the rest of my mouth.
My PCP said it looks like thrush and I was prescribed Nystatin and Diflucan, both of which didn't work. When I read symptoms of or see pics of thrush, it really does not look like I have that. I have an appointment with an ENT, but it won't be for a long time because he is all booked out. Any ideas?
