I say wait.
My quick story. I considered myself to be a a person of normal confidence (now 27). with no blushing probs. I did a TEFL course to teach english in spain 3 year ago. If I had had this problem then, I would never have dreamt about doing the cousre( I would have bottled it sure)
I started to get stressed in my classes too often when not knowing the answer in front of students. I went red and this deteriorated so that i´d go red even when they asked me anything simple. this then continued into social situations. consequently has made me very paranoid.
Most people on here have had this prob from teen years. I developed it recently. We both think the same. it´s ridiculous but we can´t stop it.
I was googling this problem ,looking for cures and read someone had hypnotherapy done which cured her. I had always thought hypno was a complete joke, but have been reasearching it and I strongly believe it can help most blushers. it is called specifically hypnotherapy NLP.
I´ve read a few people say it works on forums, and on hypno´s website´s, they explain our problem perfectly and list it as 1 of the probs they can cure. 1 site i found ,was just a dude who had these prob´s and then had NLP and just wanted to communcate his situation and cure.

I plan to visit 1 in my area in august and I will say here how it worked out.
Anyone thinking about surgery should def try hypno first. much cheaper and safer. no reason not to. If anyone has tried this then post here.
