Oh... I'm so sorry to hear about everything you've told us. I hope you have a speedy and full recovery.
I'm about to have the same surgery myself, and in a similar way to how you were operated on (I say similar because right now there's a significant crisis in the healthcare sector here, and the guarantees aren't what they were a few years ago). Now, after reading your experience, I'm actually a little scared because I had no idea the process would be so painful. Now I'm starting to get a better idea of what it's like.
