There is something that has been puzzling me for quite some time. When I was officially diagnosed with CFS, I was prescribed antibiotic therapy by my specialist. I had herxing symptoms, which obviously indicated to me that I did have a bacterial infection. On this treatment, I was slowly making progress. I am confused as to why CFS specialists would not try antibiotic therapy before antivirals ? If two-thirds of CFS patients have a bacterial infection, then wouldn't it harm them to take immunosuppressants and put them at additional risk ?
