Im having my SCS removed. There is pain at the base of the leads. The battery has moved and is bulging causing pain. And since having L3-S1 fusion 1yr ago i do not have back pain and do not need to use it. My concern is the removal of the leads. Ive had the Stim for 4 yrs. My surgeon feels confident that the leads can be removed. Has anyone had leads removed after several years. And if so, what can i expect ?
