One is a friend of mine who isn't a lady and the other who he learned from...I don't know. There aren't too many people that know this technique.

It is finger cot balloons inserted into the nasal cavity and slowly inflated using only a few ounces of pressure...inflated with a blood pressure cuff bulb...one nostril...then next day can do other nostril...then do both again and that is it.

I would advise that nobody tries this unless it is done by someone who knows what they're doing. It is a simple concept but very delicate.
