For a while now I have been experiencing bodily aches and stabbing pains. I wrote it off as nothing to worry about. Then when I was brushing my tongue yesterday, I was getting frustrated I couldn't clean it entirely. So I grabbed a mirror and tilted it up to see just how "dirty" my tongue was. When I did, I saw strange swells on my tongue. It was shaped just like a V, with the bottom of the V reaching near the back and the connecting lines, so to say, reaching off to the side. Can anybdy explain this, and whether it may be serious?
