I know this is an old post, but wanted to let you know that I pass those too. They appear to be rope parasites. Look it up here on curezone.
Have you been tested for lyme disease? Many with LD have parasites, specifically this one and tapeworms, hookworms and many other ones that often aren't identified.
I do coffee enemas and colonics to help get this stuff out of me. Been going on now for two years. Hard stuff to get rid of.
Get tested for lyme disease from a lyme literate medical doctor (LLMD). Ask for a Western Blot test and have them use Igenex labs.
