"I have this red spot on my nose, it's very sore but it seems to come and go at random!!!"
"Well I've tested you for allergies and various skin conditions and all the tests were negative! I can only think that perhaps you're bumping it without realizing? Maybe putting on glasses? Is there any activity where you might bump your nose repeatedly that you can think of?"
"I have an idea Doctor but there's nothing I can do about it! Thank you for your time! Same co-payment as last time?"
