Hello again, Steve. Typically HSV affects the skin but it has also been known to affect other tissues. It is certainly a possibility. I was unaware that you tested positive for inflammatory markers, so some autoimmune condition is certainly a possibility as well (it might not have a name, by the way . . . just "something" autoimmune). It could be that your negative ANA test was because it wasn't done during a flare-up, so if you feel that your symptoms start to wax, then I would rush into the docs office to get a blood test at that time. It sounds like your physicians have been thorough, so I'm not sure what other test can be done. I wish I could be of more help but I think they're methodically making their way towards a diagnosis. Good luck with the antibiotics and write when you feel the need.
