I VERY much appreciate you weighing in! I feel it's important to 'bump' some of these threads back to the top, because, like you said - for the sake of new folks coming here.
You're a great guy

It's surprises me how things sometimes go against what OUR 'logic' may deduce.....I really DID put alot of thought into this issue, and according to what I thought would be best, well, it ended up going in the opposite side! And I'm grateful for that!
I'm right handed, sleep on my left side more, so I thought having the IPG placed on my right side would make the most sense. Well, my battery is on the LEFT side and I'm GLAD for this! Like you, my pain is both legs, lower extremity issue, so the battery goes in hip/butt area (some Dr's place them in the abdomen).
It works great for me, because I use the handy dandy extension antena over the IPG site on the left side and am able to use the controller (that the antenna is attached to) with my RIGHT hand. Being right-handed, makes sense to be able to use the controller with the right hand.

But, even more important to me was the fact that I'm able to wear my normal pants without the battery or the scar being irritated ! Battery was implanted below the waist (which also went against what 'my' logic thought was best)....

.....aneeeway, I re-read this post and it's pretty bass-ackward and confusing ....
Bottom line: each person is different. period. different things work best for different people.....?

Ok, this has been my profound knowledge of the day to share.
Good Lord! I do apologize if this post sparked a headache in any potential reader.....
