Do you think people seeking medical advice from HN comments might be related to their disatisfaction from the suppor they receive from medical clinicians?
Yes and no. Some are just way overconfident in their knowledge of medicine and human body, while it is miniscule compared to the average physician's. Medicine is a field much larger than people realize. It is easy to think you know a lot when you don't even know how much you are missing.
Having a reason doesn't make it any less dangerous though.
