My apologizes for responding in such a tardy manner. I am seeing more come out. I've spent the better part of this morning on the phone attempting to locate what type of doctor I need to go to who can work on this with me. I know that in many cases the test read negative for parasites, but what I'm seeing come out on those occassions I use Psyllium could not possibly produce a negative test result. I'd like to know that what I'm doing is having the desired outcome. I've contacted the nearby hospital, referral services, even the CDC info line and the state and county health departments and no one seems to have the slightest inkling who deals with intestinal/parasitic helminths. I was told originally General Practitioner, then Internal Medicine, then Gastroenterologist, then at CDC I was told to contact a parasitologist. Do you or Does anyone know what type of doctor I should be in contact with? It is frustrating and surprising to me how difficult it is to find this information.
