These poor kids! It certainly sounds like it could be TMS. I hope psychological causes are being looked at, although I think it would be very hard for parents to accept a TMS diagnosis because it can reflect on their parenting. I had an alcoholic father and a controlling mother who were in tremendous conflict with each other. I was angry, but it wasn't "acceptable." My TMS started at a very young age (3 or 4) with bad headaches, "growing pains" in my legs, allergies, ear infections, frequent colds, an attack of hives. My little body was sending a loud and clear message about the stress in my life. I'm finally listening.
