If you can feel it in your lips and tongue get in the car take the benadryl and go to the emergency room before you get worse. If you are allergic to okra this instance could be the warning that you are sensitized. The next exposure could very well trigger a much stronger response.
If this makes you nervous, you could also do a DIY test in the waiting room of the ER. It could save a frenzied drive.
Your best bet, though, is an allergist. He might find something more serious that you really want to know about.
