The last couple of days I've been noticing that tingle in my sinuses again. It comes and goes, but when it is here, it's incredibly annoying and painful. I'm not congested or anything, but the last two days I've been much more tired than usual. I think I'm either getting the sinus infection again, I've got intense new allergies, or I don't know. I'm also running a low temperature. im going to take some antihistamine.. maybe it'll help.
