What is wrong with my boyfriend?
	
	
		The other day I noticed some tiny scars on the top of my boyfriends hand, and I asked him what they were from, and he said he was working on his car, and he bumped into something.  Then, this morning while watching TV, I noticed him scratching himself right at the base of his thumb, an dit looked like it was turning red, so I quickly said something, I was like "hey, what are you doing"?  And when I said Hey, and not that lound, or anything, he acted like someone snuck up and popped a balloon behind him, and was like "what? oh, I just had an itch," and then he stopped scratching himself, and I then noticed his leg bouncing a little, not very noticeable, but enough to where I could tell he was bouncing it.  I don't want to jump to conclusions about anything, so I thought I'd ask without saying what I think it might be, to see what other people say.  Can anyone help?
