You could try a travel clinic. They are familiar with parasites and can do specific tests. Also, I've heard sometimes you have to be on three or four different kinds of prescriptions to kill them effectively. One show I saw, this lady had pig Tapeworm larvae in her brain, and it caused a seizure. They did a MRI and thought it was a tumor. Upon surgical removal, they found out it was parasites and gave her drug treatment for months to kill them all, and then had to retest after six months. Good luck.
