Suggest Remedy For Hot Flushes

Hi there, for the last 3 years I have suffered from blushing in front of people and its sometimes combined with sweats, hot flushes. I am an outgoing person but this creeps up on me sometimes (in the form of me fearing my blushing or being put on the spot) and believe maybe hypnotherapy is the way or some medication at least. I really don't know why this happens sometimes and wish it would just go away. Thank you for any insight in this matter. Rachael.
