I went to the ER because of blackish discoloration on my fingers and thumb which appeared only in the winter. The ER doctor was disgusted I was wasting his time on a trivial matter. He told me I had a fungal infection & to use hand cream on it. Since then I have discovered this "fungal infection" only appears in extremely cold weather when I've had to work outside without gloves or mittens on. In fact, it only appears in circumstances one would expect to get frostbite. After looking up frostbite on the web, I realize the "fungal infection" is really frostbite. The web says frostbite is a medical emergency and one is to get help from an ER immediately. But when I did that, the doctor wasted my time and money with his inept, arrogant misdiagnosis. So, instead of me wasting his time, he wasted mine, and wasted my money too. Plus put me at further risk for having the same condition repeat, since it had been misdiagnosed.
