That's what the drs finally told us when my daughter went through something similar a few years before my stress induced visits. Hers was as well but they didn't give her the good meds like I got and she didn't need a diaper. I don't recall if they gave her antihistamines. At one point in time, one lone dr thought maybe it was marijuana sickness but to stop that one just had to shower with hot water. There's no way my issue was going to get better with a simple shower. Hers finally stopped when she got away from the stressors.
