I'm sure some doctors have drugs that will kill the worms and take care of your problem, if you find the right doctor. It sounds like you have a serious case if you can actually detect the worms outside the intestines.
I have used the ozone cysteine treatment. I continued it until the last of the cystiene was use up. I don't know if I had worms or not. On the last day I took an extra large amount of oxonated olive oil and woke up with orange oil in my shorts. I wonder hmmmm.
Even if it doesn't work for worms the cysteine removes heavy metals and the ozonated olive oil removes pcb's.
