Trust your Doctor!

I have regarded Doctors as "Super-Human Beings" right from childhood and still continue to do so. Over the past week, I learnt a few lessons as to how imperative a doctor is when it comes to diagnosis and treatment of infections or diseases and how we should not become judgmental about him.

Last week, I had a frivolous infection, but the "urge" to learn more about that, led me to the ubiquitous Internet, and when I searched about the symptoms, the never ending net threw millions of websites to which I went immediately.. They had complex indecipherable information (incomprehensible for a non-medico) and I ended up confusing myself more than before. The net warned me of blabla"phytis" or blabla"ia" for the symptoms I mentioned. This perturbed me a lot and made me pay the unwanted visit to my Doctor's.
After making a note of what my problems were, My doctor asked me a few more questions. I put forth my theory about what I read online and what my assumptions/diagnosis about the disease would be. He stared at me and asked a question which I will never forget in my lifetime, "Do you think I learnt medicine in a day? I spent more than 5 years to learn the Art. Never experiment with partially available information.". I offered my apologies to him and started back home.
During my travel, I tried recollecting where else we tend to be judgmental or work on partially available information. I was startled with the instances I was reminded of! Everyday, almost every second, we end up making assumptions, spread superficial rumours, ponder over frivolous or even non-existent thingies! The net is of course a vast information resource, but we may just use it for reference and not make any expert conclusions from that. Information from internet could be potential resources for further study, but they may not give us the complete picture. (at least at the medical and higher science levels)
Hey, I am having a swelling in my arm. Should I look into the net regarding the reasons? :)
