I couldn't agree more.
Seven years ago I began a slow decline in health that completely ruined my quality of life. I suffered endless migraines, fatigue, abdominal pain, weakness, difficulty focusing, depression, loss of feeling, and social withdrawal. I went to doctor after doctor, and each gave me approximately 5 minutes of their time and couldn't figure out what it was. Very little came up in the standard blood tests.
I had several doctors accuse me of making it up, or saying it's all in my head. Most of the rest just shrugged and sent me on my way. If I had complete trust in medicine I'd have given up and had to live with this forever.
But that's not the kind of person I am. When I felt well enough to, I researched online - examining symptoms, reading up on scholarly articles from PubMed, reading patient cases, bulletin boards. I investigated everything. And 80% of the progress I've made on my condition over the years has been due to my research. I found doctors sorely uninformed on research done in the last ten years - as if after graduating they stopped picking up anything new.
Sure there are hypochondriacs out there. But modern medicine leaves a LOT to be desired, and I'm glad as hell that I have a resource like the internet that allows me to give my condition the attention it deserves.
