Have you tried a catheter enema? for the higher worms?
I had itchy skin and I stated to use IodineLugol's 2% solution topical. Initially it hurt, but it cured me of almost all itch and sores went away! Iodine worked wonders, I still have some periodical itch skin, but almost none. I still place a few drops of Lugol's twice daily am and pm.
Since Iodine kills parasites, I have started to take Lugol's 6 vertical drops am and pm. I will increase that to 20 drops daily as that is 50 mg/day as recommended in some physicians Iodine videos I saw. It is said that we are all lacking (90%+) Iodine and there might be a link. I don't know, but since it kills the topical ropes I am willing to try. Increasing Iodine levels to proper levels takes about 3-6 months. I have done Iodine (4 drops Lugol's) enemas and ropes came out, but I could they come out with almost all enemas I used.
Today I did an Epazote herb enema and one 5" came out..
I also think they are higher up, hence the catheter enema might work but I have never done it.
