Gosh, Jim, You sure do have the weirdest things! I have no idea what that could be. As always, none of us will really know, but some thoughts occur to me...Is your tongue sore? swollen? It sounds like maybe a blood vessel burst inside your tongue somehow. Have you ever burst a vessel in a finger and had it turn dark and swell? I don't know about the bump, unless that could be the site of the ruptured vessel.....

I'm just clutching at possibilities here. I imagine that you were stunned to find this first thing in the morning!! Please keep us posted! I wish you could see someone sooner, but if things are stable right now, I guess it's ok to wait. If your tongue swells or gets really sore or darker, I sure would find another doctor to go to....maybe your doctor's partner.

XOXO--Colleen
