Hi. I'm worried I might have a lesion that could be leukoplakia on the floor of my mouth (on the frenulum of the tongue to be more specific.) At first I thought It was thrush because it would grow overnight if I didn't brush my teeth at night. I would wake up and see this white patch (3 mm x 2 mm) on the frenulum of my tongue and I'd scrape it off with a cotton swab and it would fall off very easily. It all begun when I started putting a prescription drug under my tongue (it tastes kinda sugary and minty.)

Only a little white line remains there after I scrape off the patch. I thought it would heal on its own, but it didn't. It kept growing, I'd scrape it off and it would grow again the next day until I decided to go to the dr and he prescribed me oral nystatin. After the treatment the white patches would not grow again so when I went to the specialist she looked at the floor of my mouth and she said I didn't have anything. So I stopped using oral nystatin (I took it for 4 days.)

But today it grew again (just a little) and I scraped it off, but a little white line (parallel to the frenulum of the tongue) still remains there. I'm at my wit's end because the specialist said I didn't have anything.

I used to be a smoker (I quit 2 years ago although I smoke one or 2 cigarettes every month or so.) I'm in my late 20's and I've had oral unprotected sex. I also have a few beers every week or less.

Should I worry about it? Is it normal for leukoplakia to grow fast and then to be able to scrape it off until a little line remains? I'm considering going to the dr again. Could this be some king of fungus or is it really leukoplakia?

I'm very worried because when I wake up in the morning it looks awful, then I scrape it off and it ends up looking kinda normal (only the white line remains.) That's why everyone who looks at my mouth after I scrape the white thing off, they all say I don't have anything. But I do! frown If I didn't, it wouldn't grow. Also the line is so small it cannot be easly noticed if you don't pay attention.

Any advice would be greatly appreciated!!!
