My daughter is suffering from loose bowel movements. Is it due to an infestation of larvae?

Hi doctor,

My daughter remains sick for nine months. She has chronic loose bowel movements eight times a day. She has an acne-type rash intermittently across her forehead. She grinds her teeth at night and eats sugar and salt frequently. She never feels full. She has fatigue, headaches, and shooting abdominal pain in the belly button. She took Mebendazole for three days and it has increased her symptoms. I took her to a doctor. He told me that she has Crohn's disease and the other doctor told me it is celiac disease.

Her parasite PCR shows an absence of bacteria, mucus, blood, and parasitic DNA. My doctor refuses to give medication for tapeworm as he believes that Mebendazole should have fixed it. I am concerned about my child's illness and I want to know whether she has an infestation of larvae that requires killing rather than paralyzing. My doctor advises me to take her to a pediatric gastroenterologist. She became sick after playing a recorder in music class that was not cleaned between classes and used by multiple children. She took Ibuprofen for pain and MegaSporebiotic for gut health.
