Nope, we used to get checked when we were little and given dewormer. It solved many problems, but my tummy always has felt weird, not painful most of the time. I was in a little accident last night and after about a half hour of raised adrenaline I had to run into the store and get one of those meat sticks. I was ok in a few minutes. I am 84 pounds and 5 foot 2, I burn calories just getting cold. Kelp helps.
