There is nothing wrong with obtaining additional, even false, information from any source that is available to you. (AI, Search, Websites/Blogs, Podcasts, influencers, word-of-mouth, etc)

It's what you do with that information that is important - the correct path is to take your questions to a medical professional. Only a medical professional can give you a diagnosis, they can also answer other questions and address incorrect information.

ChatGPT is very good for providing you with new avenues to follow-up upon, it may even help discover the correct condition which a doctor had missed. However it is not able to deliver a diagnosis, always leave that to a medical professional.

This actually differs very little from people Googling their symptoms - where the result was the same: take the new information to your medical professional, and remember to get a second opinion (or more) for any serious medical condition, or issues which do not seem to be fully resolved.
