2:08 am by Dany102 I don't think there is anything wrong with someone using the Internet to gain more knowledge about any specific medical or health topic. I believe most people have a vested interest in educating themselves (it's their health, after all). And blind faith is, in my opinion, a rather stupid way to approach this. The key is in how to present that (from patient to health professional and vice-versa). I understand I will never be as knowledgeable as a doctor (or some nurses), but that doesn't mean I take every words coming out of their mouth as pure gold. A certain dose of skepticism is actually healthy. And when you show up at an appointment with a certain amount of knowledge (that you have researched yourself), it only indicates you are taking things seriously. I always tell my PCP when I have "looked things up" myself. I don't self-diagnose, but I use it to learn and improve my own knowledge. Could this be perceived as challenging their authority? You bet it can. But that only points out how confident they are about their own level of expertise. The ones that gets annoyed with you only make themselves looks less professional. Health professional aught to welcome and encourage determined patients. After all, they are their own advocate. Just make sure you redirect/guide them if they are falling off the bandwagon.agree! I'm a nurse and I try not to pull the nurse card, but I also know my body and my history. Trouble is some doctors don't listen to their patients and find out their concerns. I've seen this many times working in the ED. It's mostly education. If the doc doesn't think that the dx is xy or z, than gently explain.
