Yes I've noticed when the leads moved it feels different. The first one SCS when the leads moved it felt like a 500 lb man was sitting in my chest and I couldn't breathe. It hit nerves that squeezed my chest and had to be shut off immediately. This time I kept feeling the vibration but no serious pain just annoying. Laying in bed and suddenly vibrating when I'm trying to sleep. I would feel it all different times so it wasn't just positional.

Now the Dr who installed my 2nd one will not fix the issues just remove it period. His partner said he would remove entire device and install a new one. It seems they don't just move the leads. Maybe for me it's because of where they were placed on in thoracic and one in lumbar. The entire purpose of the SCS is to get relief and let us get back to living a somewhat normal life. If we can't bend over, twist or literally have to watch every single move we make how is that a normal life. Even with my SCS I'm still in pain meds to have a more comfortable daily life, without them I would be in bed or on the couch every day. Hopefully your Dr can come up with a plan of attack to adjust your leads and not remove and replace.
