I have been having moderate to severe allergy symptoms. I have tried Allegra D, Flonase, Dayquil/Nyquil for sinus and cold, Mucenix as well as a daily nasal wash. Currently I have no running nose and can breathe through, but I am suffering from a severe pressure from my upper brow down the nose to under my eyes. Could this be just a bad case of allergies or an infection?
