Hi all. My daughter is 10 and has been suffering with exactly the same symptoms on and off for 2-3 years. It got so bad we eventually went to a private gynaecologist. She said that it’s absolutely not worms or infection if any kind. It is a form of night terror, it’s the messages from the nerves to the brain cresting the feeling. She said she will grow out of it with time. But she gave us a micro dose of Amitriptyline. We give her 1 for 2 nights in a row and it completely stops the problem for a few months. I hope this helps. We had tried everything and would be up for hours each night.
