Wow, I never tested positive for the lyme disease specific bacteria borrelia b. This could very well be the cause for you. I'll have to check if my CD57 level was tested in the past.
Yesterday I wrote a post with link to how someone here cured EC by taking the drug Lamprene for leprosy. He visted a top clinic. The post didn't mention why the doctor prescribed the drug, but I'm guessing because it was very effective against resistant bacteria infections like leprosy.
