Blushing

I suffer from sever blushing in normal situations. I could just be talking to a friend who i have known for years... I dont know why this happens, its been happeneing for about 7 years. Im 24 now, and it worse now then ever, i now obsess over it. When i wake up in the morning i fear that it is going to happen that day. The worst is when i do blush, people point it out and say why are you turning so red... Its so embarissing because i dont even know why it happens sometimes.
Can anyone give me advice?
I wanted to try eredicane... Has anyone tried this?
Has anyone gotten the ETS surgeory because thats my next option.
Thanks for anyones help
