A kinesiologist can cure you of the allergy. One got rid of all of mine.
A good initial treatment is a nasal steroid spray, like Flonase. Zyrtec or Claritin might also be effective. If medical management does not work, immunotherapy (allergy shots) might be required to desensitize you to the things to which you are allergic.
If you haven't tried anything medical, that would be the first step. You can try over-the-counter medications like Claritin or Zyrtec. Steroid nasal sprays like Flonase are also helpful, but they require a prescription by a physician. If medical management fails, immunotherapy (allergy shots) might be required.
