I can't identify what those things are, BUT I have almost exactly the same symptoms, for about 6 years, on and off. Have had many periods free of the symptoms, but I'm getting worse after I recently took strong Antibiotics for 2 weeks.
I just started two new threads asking if anybody has tried Malcolm Harker Herbals VermEze, or Unda Complex 39.
Take my advice: find a good treatment for parasites and take it soon. Even if you don't have parasites, the treatment won't hurt.
