If you have what I had, maybe I can help you, the worm is small builds a cocoon out of fungus and when they move to other parts of the body you will get muscle pain and very tired, it`s a common worm for stray dogs but Doctors have no clue about it. Although I think it`s not as common in humans, you have to take the medicine, off and on, for maybe 1,2 months depending how many you have,and to how much you will suffer getting rid of them, abendazole is weak I took mebendazole die off was next day, body pain for 2 days, never got rid off them, Piperazine taste like gasoline but worked tell me more of your symptoms if it is the same parasite I know how to eliminate it...
