Thanks ChristineB. Several weeks ago I had my Rad OC look at my tongue and he didn't think it was thrush. It's only on my tongue, and there is no associated tenderness. Also, it's been like this for quite a while and has not progressed or expanded. However, I would love to have it cultured just in case it's something like that. I will see what I can arrange.

Thanks again,
