I made and appt. to see my dr tomorow about extreme constant headaches and eye pain, I had no idea it could be sinus as i've never had it before but I don't have a blocked nose I just have these awful eye headaches and mild nose congestion. At first I thought it had something to do with the central heating because I feel so dried out, perhaps this makes it worse so today I've turned it off (OMG It's cold!).
