yeah, I second the netty pot. I get those sore throats in exactly the same spot as you do. Only thing I've found that works is quite literally "sniffin" salt water up the nose and down the back of the throat. It's really icky but works like a charm. When you get the saline in the sore spot, breathe in thru the nose so it kinda stays there for a bit. If you do this 4X a day by the next day it should be a LOT better.
