Hi ICU, I have been battling with some kind of parasite in my throat for about a year. All tests for parasites are negative. I have had quite a few cysts removed surgically from my nasal sinuses,throat and recently oesophagus. I have take albendazole for three cycles and the last time with invermectiv horsepaste. I feel the movement in my throat but not with the same intensity. How long do I need to take invermectin for to clear this infection? Should I take Prazi as well?I would also like to ask what parasite this could be in my throat? Are there any tests available to detect them. Thank you in advance for your advice.
