ECV?!? help

I'm so terrified someone please help me if you can.!! I have a breech baby and I've tried everything at home and he won't turn. So they said now at 37 weeks they can try ECV to turn him. Or I could choose not to try it and have a c section. I DONT want a c section. I know baby could turn back to breech after ECV and that don't matter to me if he does it is what it is. But I'm so afraid of the risks like what if his cord gets twisted or something bad...? Have any of you had an ECV? Let me know how that went. Plus don't tell me it hurt lol. They said they offered anesthesia at my hospital for pain and muscle relaxer so I won't feel much. Just wanna know if any of you had this done and it be successful and gave birth.?
