Yeh I was told Panadine was ok too by the chemist but only for a short time. I had a wisdom tooth out about 4 weeks ago now and ever since then the sinus has just gotten worse and worse. I looked it up on the internet and apparently your wisdom teeth are connected in some way to the sinuses. It never gave me any problem though and was a sinch to pull out as well. Must have triggered something though cos this is insane.
