What do i need to know about banana allergy?

Avoidance: As with any food allergy, the only treatment is avoidance. However, if the allergy is mild (e.g., little more than itching in the mouth when eating it), it may be a cross-reaction from a ragweed allergy. If that's the case, allergy injections will very likely make the itching go away. See an allergist for skin testing, so you can find out what is really going on and what you can do about it.
