Doctors

So. For the past two weeks everytime that I lean forward, or slouch slightly, my left arm goes completely numb. I go to the doctor and wait in the waiting room for 2 hours and then he tells me that it's just a mechanical problem and I should sit up straight. Looks at me like I'm an idiot.

This is why I don't like going to doctors. I guess that this is the type of thing that a person is supposed to just ignore then?
