Misdiagnosis
I was attacked by my dentist, and ever since that day, my view of doctors has been tainted.
I had gone with my mom to the dentist. I think I must have been in my early teens. My mom was in another room having her teeth cleaned by a dental hygenist, and I was in a chair being examined by the doctor.
Of course, I have weak teeth, and that usually meant every visit to the dentist was worth a new filling. This trip was no exception, but the doctor told me that it was not a big cavity, just a small one that was easily fixed. Easy, except that the ordeal ended up with me locking myself in the car to get away from him.
