About 2 yr ago, I woke up lying next to my husband (then fiance) and my tongue had swelled so much that I spoke like Corky Thatcher from a 90's t.v. series. It took about a month or two for the swelling to go down enough where it didn't distract me into playing with the lump. It was in the middle or between the top and bottom layer of the tongue, as well.I went to my physician, and wasted a few hundred dollars for him to tell me he had no clue what it was, had never seen or heard of anything like it and to keep a close eye on it. I still have a hard lump in the middle of my tongue. Every now and then it will swell up, but usually "deflates" itself. All I can say is warm liquids, and Ibuprofen seemed to help.
