Good luck, vch. I had two doctors in the emergency ward of local hospital try to commit me to psychiatric ward when I went there very ill with parasites. Count yourself lucky that hasn't happened!
I wrote a letter of complaint to the hospital. The two doctors were not qualified to carry out a psychiatric assessment. They were hopeless.
I have similar symptoms to you. I've been trying to find a company that ships Safeguard paste here to Autralia. The drug in it, fenbendazole, has worded well in animals.
Also, have you looked into PDC (Parasitic Disease Centre, in Georgia.) Irving Kaplan Ph.d. developed blood tests for parasites. I'm wondering if anyone has tried these blood tests.
