I got a canker sore. It's been really painful that I cannot enjoy hot coffee (so I drink it lukewarm). Did I eat only something particular? I tried to eat everything from my farmer (this week, we got lettuce, onions, potatoes, zucchini, daikon radish, and cabbage. I addition, I've bought some tomatoes and cucumbers with different kinds of fruits). I've had some cheese, meat and milk.
Anyway I hope it's going to go away really soon. Hate ulcer!
