Does anybody know of anything that is safe to take during PG, for sinusitis?

I've never had it before, but I think I currently have it. I've had a really heavy cold for the best part of a week, but now the right side of my face/head is aching (even a few teeth on the top on the right hand side, right down the back) and there is a real 'pressure' feeling. When I blow my nose, a lot of it is clear, but there is also a lot of white stringy/gluey type stuff....(sorry TMI!). It also hurts a bit when I blow my nose.

Does that sound like sinusitis??? Panadol isn't giving me any relief whatsoever.
