I have two leads on my SCS- a laminectomy and a regular lead. My battery pack is in left hip. It's doing well now, but I have had quite a few revisions on it. A few years ago my hip started hurting like crazy, and they figured out that I had a few neuromas around the scar tissue. So the removed those. Then my hip started swelling up and hurting an insane amount. Turns out that my battery had moved and was pressing against my hip bone. Ick. Now my battery is in a dacron pouch. It's a synthetic material that the scar tissue grows into so nothing can wiggle around. And it's been really great for the past two years! At some point I want to get a smaller battery, but no one is quite sure how the dacron thing will work with a smaller battery. But it has worked well.

So my long drawn out point is that things can go wrong that are not RSD and can be fixed. Talk to your doctor about it. And my battery pack can go through periods where it is more sore. It can be a little worse on some days, and a lidocaine patch can help a lot with that sensitivity.

Hope this helps!
