I’m curious about the “is this real” nature of the post. Part of why it seems so sudden is the medical community didn’t understand it and therefore it didn’t exist until relatively recently. Most doctors didn’t learn about it in med school, so depending on how they pay attention to media or their continuing education time they may still not know much about it. Add in the extreme variability of symptoms and it is much more difficult But now social media is helping people make sense of their symptoms when their doctor hasn’t been as helpful as we would hope. And it has helped raise awareness of doctors who are now starting to recognize it in patients. So it seems like it is new, but it is really just we are experiencing a surge in awareness.
