I think I can trace it back to last night when I used some Crest mouthwash. I may have used it longer than the recommended swishage duration time. This morning I woke up to a little sensitivity in the aforementioned area. Then without warning, I ate some tri-tip, flour tortillas, and some SALSA. SPICY SALSA. This fiery extract of pepper pandemonium reached my enflamed area and proceeded to burn the living f**k out of me. How can I soothe and heal the pain?
