Hmmm... bumps aren't great, but they could just be a reaction to something like citric acid s (lemon juice). Keep an eye on them, try using a bit of coconut oil on them, and if they persist longer than 2 weeks you may want to get them checked out.

The sides of the tongue can represent the lungs - were you ever a smoker?

An Irridology reading might be a good idea if they persist as that would let you know whether the bumps are representing another part of the body.
