I am back home! Everything went well! The first part of the operation went better than first time. Of course it was painful again, but shorter. I sure did NOT feel lonely in that operation room; there were at least 4 extra surgeons, who almost didn't stop talking in English! Why? They all were there to follow and learn all about this new kind of operation.
I am so happy that it is all over now. But I cannot tell yet if it will be a success, because the doctor still has to "activate" that neurostimulator. This will be done during an appointment on monday morning 11am.
