I think I'd rather find solutions to the problems I already know about than go looking for more problems.
Perhaps you are a bit like me, and you don't like dealing with the whole tiring mechanics of doctor visits, blood tests etc. In my case, I often just order the drugs online, and try the treatments myself, being my own doctor.
I would not mind going to the doctor if I could see a good ME/CFS specialist, but in the UK there are almost no good ME/CFS doctors, so it becomes all the more tiring to have to explain everything to my primary care doctor who has very little knowledge about ME/CFS treatment.
But you should be aware that the way non-ME/CFS doctors interpret viral blood tests is different to the way ME/CFS doctors interpret them.
ME/CFS patients often have little or no virus in the blood (hence negative PCR blood tests), but their IgG antibody titers are often high. To a regular doctor, this does not make much sense, so like your doctor did, they will scratch their heads, and say "that's weird", and then just ignore it.
But to an ME/CFS specialist, those high IgG titers suggest an ongoing infection may be hidden away in the tissues (rather than the blood), and they will treat with antivirals or immunomodulators.
I am not sure if your elevated VCA IgG is high enough to be considered an active EBV infection, because this interpretation really needs to be done by an ME/CFS specialist who is familiar with this testing.
But certainly you can pursue other theories of ME/CFS and other treatments.
