Anyone every had a tooth extraction around the same time as having a sinus infection?

I'm just getting over a sinus infection (been on Augmentin 875mg twice a day for 6 weeks) and now I need to get my wisdom tooth pulled this Thursday. I e deep cavity (root exposed) done on the same tooth #16 in August and things haven't been the same. At that time my dentist said I might need root canal if it cause me discomfort but have decide to just remove it. Ever since i had the tooth filled I have had sinus pressure , sinus headaches and now this horrible sinus infection. My only concern is that I think my root is near my sinus cavity and is it ok to pull the wisdom tooth after having had a bad sinus infection?
I'm still on Augmentin for another 2 weeks!
