My throat is not sore, but my tonsils are very swollen. It seems like it gets worse after taking Allegra, and it did when I was on Nasacort previously, too. I have terrible allergies, too, and trying NOT to take the Allegra (which I just started, and bought a couple bottles of) is proving a very mixed blessing. My sinuses are all stopped up, and my throat is swollen - but I don t feel the slightest bit sick or sore besides that. How do I verify if it s a medicine allergy?
