Anyone notice a connection between eating spicy food and PN pain that follows about 30 minutes later?

I was trying to do the "no nightshade" diet which means no potatoes, tomatoes, eggplants, bell pepper or any other kind of pepper (black pepper is okay). I occasionally slipped but did stop buying and cooking with jalapenos as much as I had been.

I recently started buying jalapenos again and cooking with them, fresh minced, about one (with seeds and membrane removed) per 4 servings in my stirfrys. The PN pain afterwards definitely does seem to increase.

I'm wondering if there is more to this "nightshade-free diet" than I thought related to PN. It is touted to help with arthritis for many people (though not all). Maybe it helps PN too? I hate to give up my jalapenos.

Anyone else see a similar connection?
