Thanks Faith!
My daughter first started out sort of squinting and then huffing back at about age five. The squinting never really stopped, but it was pretty unobtrusive and never seemed to bother her too much; when I initially made her aware of the sound she was making (thinking of it as just a bad habit) she was able to stop doing it. Since then we have gone through lots of different sounds and movements, on and off... humming, squeaking, sniffing, and the squint turned into more of a grimace. It had pretty well resolved by the end of last summer but then it started getting worse again, and now there has been a huge flare-up just really in the past couple of weeks, since Christmas. Now she's both blowing on and smelling her fingers -- putting down what she's holding to do it -- and twisting her head around to the side so far and so often that her neck hurts. The problem seems to be worst when she's playing video games, or reading or being read to, or to a lesser extent when she has to try to carry out a complex task or if she feels stressed about something.
Some of her teachers have also started identifying some pretty prevalent behavioral issues, although according to them she is a very sweet girl, extremely funny and really smart. A friend of mine who works with special needs kids thinks she might actually be Aspergian. So that's another whole angle I'm tryng to get my head around.
So far I'm afraid I have done nothing other than severely freak out and try to get a grip on what this could be and what it all means. I somehow have the idea that an allergy / sensitivity panel should be done first, before eliminating a bunch of stuff from her diet and environment, just to keep things straight. We should be able to get that taken care of in the next week or two. From what I read here, I'm wondering about doing the strep tests next.
Sorry about that -- family physician (GP).
