sinus symptoms

What if it's histamine?

Do you experience allergy symptoms, but no allergy has been found? Are you quite sure that you are reacting to certain foods, but can't pin them down because you seem to be fine with the suspicious food one day, but react on another? Maybe it's not an allergy, maybe it's histamine intolerance. Not great if you've got it, but you may be able to do something about it.
