The post made on corner tips is a great effort to give those with zero idea of what is needed to help their fighter in the cage. My hope is that someone in that situation would not simply take such tips and run with them as particularly with fighter injury and related medical issues (cuts, swelling, etc), it should not be handled by those without proper training. The sport is trying to increase on a growing position reputation, and random attempts at medical treatment won't help the cause or the fighter.
Some of the things that are misconception include water use (your fighter is not going to likely dehydrate, and certainly won't avoid that with a sip of water during a 45 second intermission), ice use (there are specific locations where it is best applied, and the back of the neck is not the first choice even though it is seen often during fights), and enswell use (that is an art in itself and can easily be misused). Prescription medications are limited in that way for a reason, they can be used improperly and cause injury, so I hope corners won't try and access it illegally if they aren't trained and knowledgeable about pharmacology. Unfortunately many cutmen in the world aren't either.
Despite that, if promoters know that cutmen are wanted at fights, they few out there can better be present to help at shows. And hopefully all of us want to improve, including corners and coaches.
