This is where it all gets confusing especially to doctors, but it's what makes them excited about GET. They incorrectly assume that if someone gets better from exercises, then this approach will work for everyone.
They don't even know if the people who got better had ME/CFS in the first place. People are misdiagnosed on a daily basis even with more simple diseases. PEM descriptions are still only descriptions because everyone perceives their fatigue or pain differently, meaning someone's fatigue which looks like PEM may not be the same as ME/CFS PEM.
If someone gets better after exercising and can increase their limits, it can mean a few things:
1. This is not ME/CFS and never was
2. It is ME/CFS in a temporary remission phase, happens often especially in early stages
3. It is ME/CFS but leading to a permanent spontaneous remission, it's rare but possible
4. It is ME/CFS and someone is on a protocol that works and cures them
By definition exercises are NOT THE CURE for ME/CFS. If they cure someone, chances are it wasn't ME/CFS at all.
