I went to the clinic for an ultrasound, the doctor told me that I had a pinworm in my bile duct, gave me two injections to let the worms get a place to turn my head down and gave me 2.5 days of medicine to drink. It helps me when I lie down, but it hurts to walk, I have to go hunchback to be comfortable. I was treated for a day and two nights. So the doctor told me how to treat men with pinworms entering the biliary tract? Thank you doctor.
