Sharing the toilet: It's ok, but frightening, to share a toilet with a worm, as long as the worm was already there. However, if one believes the worm just came out of her body, she should try to capture the worm. A patient's primary care doctor can order a "worm ID" or "parasite ID" test, and the patient can drop the worm off at the lab that received the doctor's order. Hopefully, the worm was from somewhere else.
