M.P.
I'd wait and see if it happens again before I tried changing anything.
I and my family have lots of allergies and this doesn't sound like an allergy. An allergy usually results in itchy hives or at least itchy skin. The skin doesn't hurt.
But, yes, you can develop an allergy after having safely used/eaten the same thing for years. I had no allergies as a child, young adult. Then I developed food allergies. Now, in my later years, I don't seem to have them as much as before. It's all a matter of how your body's chemicals react to the stressor.
