if you are genuninely interested, then I can suggest a few things to look into, perhaps a good place to start would be , Dr Klimas who has been working on the illness for many years, she studies 2 illnesses HIV and ME/CFS, she is on record saying that if he HAD to have one, she would choose HIV (please note she is referring to HIV not late stage AIDS) she is considered an expert in the immunological aspects of the illness.
Also you may be interested in professor Newtons work on autonomic dysfunction problems and PH anomalies in the muscle.
These are 2 well known academics that are connected to universites,
I can think of hundreds of other papers and leads, there are papers on heart anomailies, immune problems, muscle problems, endocrine, neurological etc, please someone correct me if I am wrong but I beleive there are over 4000 papers published on biological anomalies in the illness, (this should go some way to explaining why patients are extremely fed up of talking about psychology)
There are doctors around the world using various treatments but there is yet no golden bullet, but some of the treatments are antivirals, antibiotics, immunemodulators, endocrine treatments amongst others. I hope this is interesting and enlightening
