Hi. I noticed you mention Lyme was ruled out.  I have neurological Lyme and am being treated for it.  Over the course of 2 years, I saw 14 doctors and no one knew what was wrong and most tried to dismiss it as stress.  One thing I have learned is that Lyme cannot be ruled out by testing because the tests are too unreliable.  In order to be properly tested and diagnosed with Lyme, you must find a Lyme specialist.  He will treat you regardless of the test results because they know that Lyme can evade detection in both blood and spinal fluid.  If you improve on antibiotics, then he will continue to treat you. There is also the issue of the dangerous co-infections that can occur with Lyme.  Again, only a Lyme specialist can make these diagnoses because doctors are not schooled sufficiently in Lyme and its treatment.

Here's a symptoms list.  You may want to revisit the issue.
