What is up with Kit?

She's been really fussy the last couple weeks. I know she's been teething but it is getting ridiculous. So anyways, she was actually PRETTY good last night, in that she wasn't screaming continuously if I wasn't holder her. We get home and I'm changing her for bed and I notice her body feels really hot. Now this isn't that unusual plenty of times her torso will feel very warm to me but when I feel her forehead she's fine. Last night, however her forehead was feeling pretty hot too so I take her temperature.....102.9 Besides the fussiness she didn't seem sick...no pulling at the ears, no runny nose. It's 11pm and there isn't much I can do anyways besides pump her full of motrin and tylenol. This morning the fever is still down, but she was up multiple times last night. Don't know whether to take her to the doc or not. I wish she could tell me what's wrong.
