Not Wyoming related but the Cowboys faced Fresno State in the New Mexico Bowl last year and I like to keep up with him. I think he'll have a great career in the NFL but still very glad that he couldn't get past the Pokes Defense Line in overtime of the NM Bowl. Plus the Bulldogs are joining the Mountain West.
So apparently Mathews has had an issue with nose bleeds throughout his career and the his most recent gusher occurred after taking a hit against the Dallas Cowboys over the weekend. So the solution to this problem was to have his nose cauterized in what is described as an "uncomfortable" procedure.
So what exactly does it mean to have one's nose cauterized? Well since you asked...
According to Wikipedia:
If a person has been having frequent nose bleeds, it is most likely caused by an exposed blood vessel in their nose. Even if the nose is not bleeding at the time, it is cauterized to prevent future bleeding. The different methods of cauterization include burning the affected area with acid, hot metal, lasers, or silver nitrate. Such a procedure is naturally quite painful. Sometimes liquid nitrogen is used as a less painful alternative, though it is less effective. In the few countries that permit the use of cocaine for medicinal purposes, it is occasionally used topically to make this procedure less uncomfortable, cocaine being the only local anesthetic which also produces vasoconstriction, making it ideal for controlling nosebleeds.
So I doubt they coked him up to help deal with the pain since that would violate the leagues drug policy. I'm sure it hurt plenty to have a white hot poker or acid stuck up your nostril. Yes, I would say that does qualify as uncomfortable.
