Thanks Newport. I've actually suspected that I have Lyme's too. I tested negative for back when I thought I got it. I actually tested negative for parasites too though and I know that I have them. There isn't a testing lab in the country that I trust for the testing of parasites or Lyme's. Not all parasites lay their eggs on or near the butt which is how these labs test.
This one outside of my intestinal tract is a MAJOR pain. I'm running out of ideas. I'll look into the Lyme's links, thanks.
