Other than the normal surgery pains which was minimal no not at all.

It an in and out procedure. After the op, I didn’t have much trouble. One of things I noticed right away was, at times I would cough and my voice would crack when the electric surge was triggered to the brain. It didn’t take long for my body to adapt to it . When I did get use to it , I would forget that I even had it, unless I started to play with the battery box near my chest. Even when my Dr. Would level up the surge , I didn’t notice anything different.

I've had mine for 5 weeks now. It was installed turned on. No problem with the unit post op. My chin. I think they hit a nerve my chin was sore and numb. Now it's just numb.

Just don't lift a lot. I had some small blood vessels leak so I ended up with a big pocket of blood and had to go in and get it drained. They kept me for 2 days to be sure it stopped bleeding. So take it easy. I overdid it.

No I didn't before it was turned on.
