I find myself strongly doubting your claim that you're a doctor, Biff, with the language above where you said "to make an accurate diagnosis." Your haphazard grammar and punctuation, too, betray your claim of having been a strong enough student to make it into med school.
Well I was going to tell you it sounds like cancer but that would be quackery!
You should cut it off just below where the pain is!

Just make sure when you pray that it's the RIGHT Gawd!
Good Luck!
