As far as I know, I've never been tested on the NHS for all the viruses that people mention on this forum such as HHV6 etc., let alone been treated with antivirals, despite having a sympathetic GP. I had a referral once to an immunology consultant who took a history, said that I was clearly suffering from a repeatedly reactivating viral infection, and promptly sent me to the local ME/CFS clinic for some CBT/GET. Has anyone in the UK attempted to get a battery of tests for these various bugs and embarked on antiviral therapy? I seem to remember that Jonathon Kerr was involved in some research that basically cured some people who had tested positive for HHV6 (fuzzy memory of this) but I got the impression that such infection was relatively rare even among CFS patients so didn't follow up. I've been a bit lazy on this! Does anyone have any experience? Either on the NHS or by going private?
