No, I don't feel any bumps. The way I found out about it was by moving my tongue around my mouth and I felt somethning rougher than the soft tissue in the mounth. When I took a closer look I saw it is white. It is barely noticable if you don't know what you are looking for, but by the description found on the internet I think it is Leukoplakia, it may be something else, I am not sure. The lump I've got ot the inside of my lower lip worries me more actually, but I'll see. I have appointment with my dentist and my personal doctor on Monday so, untill than I can only guess what and if somethning is wrong.
