I've been having problems with my mouth for about a month now. It first started out with painless ulcers on the floor of my mouth and a whitish appearance on the inside of my cheeks. I went to an ENT and he prescribed a dental steroid that I applied to the ulcers. Within 4 days, the ulcers went away, but the whitish appearance on the inside of my cheeks remained.
Then the tip of my tongue started to feel burnt, even though I hadn't burnt it with food or liquids. That eventually went away after about a week and a half, then came back for a week, then went away.
Now for the last 2 weeks my tongue has been swollen. At first my tongue felt sore and there was a tenderness right under my chin, but no swollen lymph node. I went to the ENT again and he prescribed a oral steroid, prednisone, which I took for a week. The soreness and the tenderness went away, but my tongue is still swollen. I can eat and drink just fine. I'm rarely drink (for the past 3 weeks, not at all) and don't smoke at all.
My doctor is baffled and recommended blood tests, but prescribed diflucan for 2 weeks, just in case it's a fungus infection. It's been a week on diflucan and there's been no change in my tongue. My doctor doubts it's cancer because I don't have any other symptoms such as fatigue, bleeding in the mouth, weight loss, sore throat, etc. Any ideas as to what it might be?
