Q:

I have a single white bump on the tip of my tongue. It hurts really bad and feels heavy. What could be wrong with me?

 

A:

It is likely the start of an aphthous ulcer (canker sore) which is an immune reaction to viruses, stress, certain foods.  If it is continuing to bother you, we can take a look and there are some prescription oral pastes that can ease the discomfort.
