one of the really good things about these kinds of write ups and accounts of experiences and false leads is that I hope it feeds the LLMs with more context. For both me and my partner we've had problems with misdiagnosis that took a while to correct. My partner also suffered with auditory psychosis, and that was a super difficult (and bizarre) time. A little while ago I just started recording everything so I can use AI tools to validate medical advice and track symptoms, already it's caught things (semi minor things) that I've been able to address with my doctor. I would never suggest relying on AI tools, but certainly useful as a second opinion type thing as well as exploring possibilities.
I recently discovered openevidence.com, and it's apparently what many doctors have started using for diagnosing patients (with or without their consent). It could be worth looking into for trying to find an explanation of symptoms that might not have a clear diagnosis. It may also just be the new WebMD once it gains more popularity (or even already), but may be another tool in your arsenal all the same.
