Eye pain, facial discomfort, sinusitis?

I have recently had acute sinusitis and was prescribed a course of antibiotics. The infection started to go about a week ago. My symptoms gradually decreased but now I have an annoying pain in my eyes, facial pressure/discomfort just below my eyes and around my nose and mild headaches. I also still have a runny nose (gross I know but I didn't know how else to describe it) which leaves occasional unpleasant smells. They never last and go completely when I blow my nose. Could these symptoms be just the last traces of the infection? None of the above is unbearable but it is very annoying. I have to fly in just over two weeks and am worried about being in pain during the flight. Should I go back to my doctor? Could anybody provide any general advice on this subject? Thanks! :)
