Painful mystery bumps on tongue?

Started with my wife - she got 3 painful bumps in tongue which later turned into little white spots. Fairly painful. She also complained of the roof of her mouth feeling like it was burning. Doc gave her antibiotics which after taking seemed to help. Then after about a week I got the same thing, only my were accompanied by swelling on left side of face (ear and just below), fever (100.1) and diarrhea for about a day. I have one bump on the tip, one underneath and one on the side. The bumps are on the inside so they aren't really noticeable by looking at them. My wifes bumps started the same way but it later turned into an ulcer-looking thing on the tongue, then went away. I do not have the burning sensation at the top of my mouth like my wife did. I am currently on antibiotics (3rd day). Problem is that my wife is starting to get her bumps back. I ume my wife gave me whatever it is so it appears to be contagious. Doctor office and mouth specialists haven't seen these symptoms so it doesn't appear to be widespread. Any one have any ideas?
