Niggling headache

I've had a consistent ill feeling in the mornings for the last few days. I wake up lethargic and sore-headed. I do things to make me feel better and they do, for a while. Then, by evening, I often feel bad again. I'm perturbed by the waking up feeling bad thing. Hot baths seem to help. I am having sinus goo issues as well. Rob suggests that it may be related to some sort of allergic response to either pollen or, more obviously, dust. I'm going to do some sinus cleansing, see if I can't get this head thing to clear up since it's negatively affecting my total sense of well-being.
