I remember reading up a funny meme one time about medicine. It went something like, "Have you ever looked up a illness online and found that many cases has the similar symptoms as yours, which makes you think you are dying when you aren't?" Honestly, I would not trust Google or Wikipedia for medical advices. It is always changed or edited just to scare viewers. Always, trust medical professionals on anything. They studied and experienced more. π
Yeah, google can be tricky. I have a lot of clinical experience from my time in the military, have access to Uptodate and VisualDx, and still scare the crap out of myself.
