My friend has been dealing with this and pounded all the natural treatments with no effect. He did do a salt water with vitamin C (lyme protocol) with success. He is now on Vermox and thinks it is helping. He just finished a 3 day treatment and can still feel it moving in a muscle. Assuming that they disseminated. Albendazole may be another choice.
It is possible that they may have disseminated - you may have killed them off in the gi tract. If you want the contact info on my friend in which you could trade info send me a message on the CZ contact.
