Hi, I need some help please. Back in December 2014 I noticed a painful bump appear on the left side of my tongue. It went down two days later. Then a bump sppeared on the right side and after 2 days it went down. During December ulcers apoeared on the sides of my tongue which had a yellowish centre. They always arrive in the afternoon and are gone in 2 days. However I can get up to six ulcers on the side of my tongue at any one time. Always down the sides. The ulcers are painful and cone on in the afternoon. They start as a yellow filled bump but by the following day its developed into a usual looking ulcer, 2 days later each one goes. This has bern going on for over 9 weeks now. The bumps never appear in the same place. Any idea how I can get rid of these for good, they are driving me crazy.
