Assuming this really is sinuses, your doctor is protecting you from yourself. Taking antibiotics for sinus infections kills off your beneficial organisms that protect you from both congestion and sinus infections, and generally they go away on their own. If this is really sinus problems you want to find out why you're congested -- not easy, but it could be a food allergy such as wheat or dairy or many things. In the meantime, there are natural remedies for congestion you can investigate and you might look into using a netti pot -- basically putting salt water through your nasal cavity to fight off pending infections. Good luck.
Ok but tonight Ive been up late because of my school work for two weeks plus these sinuses have been hell:/... When I moved my eye too fast it felt like something moved out of place or out of the socket so I put everything down and layed down because that was scary it doesnt hurt now it just felt weird and uncomfortable for a second im putting ice around it right now :/
