Hypermobile Ehlers Danlos (hEDS) can cause Small Fiber Neuropathy and back pain, as well as poor healing from surgery. It’s also more common in engineering type people, higher IQ, ADHD, anxiety disorder etc

It’s probably the most under-diagnosed condition in general. It’s also autosomal dominant. Can present as psychosomatic - gaslighting from doctors is typical.

It’s a shame more people don’t know about it because there are ways to effectively treat it - it’s an area where patient communities are far ahead of the medical community. So this could be a failure on two fronts, a failure of insurance but even if they had unlimited coverage there still would have been a failure in treatment.

You are talking about schizophrenia, right?
