Can Tapeworms In The Stomach Infect The Intestines Too?

I was injured in an automobile accident a few years ago. My left upper abdomen was injured by my seatbelt/restraint, and I received a few cuts and bruises as well. I was given antibiotics and fluids while being treated at the local E.R., and I was x-rayed, had a two CT scans of my torso, an upper endoscopy, a virtual colonoscopy, and I also had a sonogram to try to identify why I am still having pain in my upper abdomen. One other problem that was discovered by one of the five doctors that I have seen for this condition, was that I had been carrying a pork tapeworm for quite some time. I was given antibiotics and and an anti-parasitic remedy that contained black walnut and various other ingredients to get rid of the tapeworm. I passed what appeared to be a tapeworm after taking the anti-parasitic pills, and have not seen any sign of the tapeworms or eggs in my stools since voiding the organism. I still have upper abdominal pain, and I am wondering if the infection could have made it into my small intestine?
