School cramps

Today I got the worst cramps in the middle of the school day. I couldn’t go to the nurse because if I did I knew the only hung they would let me do is use a heating pad and that takes too long to work. I had a very important test today! Luckily they went away by the end of the day, but at lunch I was literally doubled over in so much pain. Anybody else had that kinda day or was it just me?
