There are hundreds of accounts of people who have had substantial recovery (thought probably not full) from ME/CFS. The problem is that what works for one person doesn't work at all for 99% of other sufferers. Some people say injections of B12 fixed them up; others move to the desert and get away from environmental issues (and perhaps stress); others benefit from a very gradual incline of exercise; a few have had spinal fusions; and so on.
My wife has had ME/CFS for more than a decade. Honestly many of the touted remedies she finds online sound like snake oil, but if you are suffering and nobody has a good clue, you try each one in turn hoping you might be one of the lucky people who responds to a given modality.
Cort Johnson runs the website Health Rising, which acts as a clearing house for recent news about ME/CFS (and recently long covid as it relates to ME/CFS) and there is a community built around that site.
There is also an interesting book about a recovery in the dessert “through the shadowlands” by Julie Rehmeyer. Just not practicable for everyone, especially when the dessert is far away like in Central Europe.
There’s a very good subreddit where people share news and their experiences. There also seems to be some overlap between CFS and long covid, Dr. Resia Pretorius has published a lot of work on micro clots in the blood and long covid.
