but he's now had same symptoms x3 in 3 weeks. Begins with stomach ache, normal poo, slightly runny poo, huge vomit, very runny poo. Correlation between eating quite large meals but he often does. It doesn't happen every time after eating a large meal. I thought the first time was a bug, then it happened again and I thought he was just unlucky. And now it's happened and we are away. Someone mentioned appendicitis but the pain is in the middle of the stomach. Any ideas or similar experiences? I know three people who've recently died from stomach cancer so feel a bit on edge. Will go to GP Monday but just wondering.
