Kanker Sore Help? Is this a bad idea?

Now this sucks. I LOVE spicy foods, and I have a kanker sore that hurts at times in the bottom left side of my gum. Note, this is on the bottom. I want to eat a pepperchini, a mild pepper, well, mild for ME. Should I try one? I ate Tacos earlier, with hot sauce and Ididn't notice any pain.
