What is this? Long string on side is elastic, so disregard that. I think I have been fighting pinworms. Did 3 day treatment of pinx 6 days ago. Is this die off or larvae? Did not have symptoms for 4 days after pinx treatment, now this. Docs have had me on 3 - 3 day treatment of Alinia. Helped but not gone. Done one day treatments of Albenza, pinx. Now new infectious disease doc is putting me on a 7 day treatment of something I haven't got yet plus one day treatment of Albenza. He says if this doesn't work then lower intestinal exam(like colonoscopy). Don't think he believes me. Says husband and I can have sex and kids don't have to be treated any longer? This is all so confusing. Waiting for Albenza for ICU's treatment to come.
