Sinusitus can be really painful :(

Last night I was in so much pain I considered going to the hospital if the panadeine didn't kick in soon. I was also in a lot of pain yesterday afternoon, but it got worse and worse as the night went on and each time the pain drugs wore off, it just became so bad and almost unbearable.
I'm currently on antibiotics for my sinuses, they have been playing up for several weeks and I finally went to the Dr's about it. Yesterday morning I woke up with a sore upper left jaw, along the bone line. During the day it progressively got worse and by 1am it was beyond tolerable. Laying in bed and waiting for the pain medication to kick in was just awful and I did contemplate calling an ambulance, but I figured I should wait long enough for the drugs I had already taken to kick in and thankfully they did after about an hour, but it was an extremely awful hour.
I know it was related to my sinuses as when I moved from side to side or moved my head, the pain moved and changed AND today I woke up with no pain in my upper left jaw - so bizarre!
I see it as a sign that the drugs are actually working, I just hope that if there is a next time then it doesn't do it in this way!
