Bump On My Palate Hard Bump On Palate Of Mouth?

Hard bump on palate of mouth? - bump on my palate

I have two small bumps on the roof of my mouth. They arent discolored and a little hurt. I had to disappear a few times before and they tend to. They are hard and do not believe that you are filled with all kinds of pus. I can not go to the doctor because I no insurance Nonte. Is this something I should worry?
