hi ~ i had the SCS implanted for 6 months, but it had to be removed because i didn't have enough fat content in my body to hold it in. in other words, the generator tried to work itself out. ick. so then they did the trial for the morphine pump, which made no sense cause it's 3 times the size of the SCS.
go figure. anyway, it worked wonderfully, and all my pain was relieved. i was delighted, but then they told me i couldn't have it. lol
so if i were you, i'd go for the pump, as the SCS just irritated things more for me. it made my sciatic nerve hurt even more.
just my 2 cents.
best of luck. hugs, lee
