I have suddenly been suffering from nasal polyps. Could I have suddenly developed an allergy to soy, to which I ve never been allergic before; splenda, which I ve only recently started using; and/or aspirin sensitivity, which has never before caused me nasal polyps? The reason I ask is that they went away and now returned with a vengeance, and those foods seem to be the only possibilities.
Yes it depends on immunity if your immunity goes down with age the same things can cause allergies to whom u were not you get your blood serum test for specific antibodies for foods and medicines you are getting doubtful and you will know which medicine and food you are allergic BTO
