what type of surgery are you looking into????? MVD ,Gamma??? neither of those are 90 % successful I hear equal good and bad on both of those but maybe you are looking into something different??
please please get all the info you can about it before you have it done.I have you in my prayers and positive thoughts for everything to work out and for you to find a way to control this T.N.monster.
I have a SCS for my pain and it has saved my life , given me my life back . it is a last option .I hope you find control before reaching that point!

have you in my positive healing thoughts and my prayers also.
