I understand it hurts a LOT, and all I can say is if insurance is a go for a Trial, that procedure can reveal to you the entire picture whether your doc's comment was on target or way wide...... One thing you need to know though, is you are slender enough with your frame, you might find the implant of a generator in your hip [the usual place] to be uncomfortable. A skinny bum is a hard bum in which to hide a generator.

My backside is quite ample, and hides my generator well while it has provided me the comfort of having the SCS which has restored my life. Ahhhhhhh.

Trial is the way to find out,
Yup,
