It turns out that I am magic! My unicorn horn has been deemed an insignificant benign osteoma. I deny that my horn in insignificant and is definately magical!
It was a relief to find that it's nothing to worry about. I did find out that I have chronic sinuitis and am on some crazy antibiotic that they also give to people who've been exposed to anthrax! It's tearing up my stomach so perhaps I'll lose some weight while I'm on it these next two weeks.
Thanks for your support through all of this!
