Quoting Steffie101:
“I can’t tell you how many people I’ve had walk through the doors at my doc’s office with LEGITIMATE MEDICAL ISSUES who talked themselves out of treatment because they are self described ‘hypochondriacs’, ‘drama queens’, ‘head cases’, etc. My doc always says “You have to give me a chance to save your life.” and I believe that for any one with any kind of issue. Even if 80% of the time, it’s ‘nothing’, that means 20% of the time, it’s SOMETHING. Go and be assessed. All that you have to lose is a copay, basically. “
Those are the words I really need to hear, and I thank you SO MUCH for saying this. I’m one of those people that HATES going to the doctor unless I can be absolutely sure I have a “reason” – and somewhere along the line I have managed to equate “reason” with “positive diagnosis”, as if I am somehow a foolish person – not to mention a horrible person, wasting the doctor’s time – to have something checked out that turns out to be nothing. Have I mentioned my million insecurities? 
Your post was extraordinarily reassuring.
