Yeah, I can't find much info about keyhole anywhere, so I want to eventually document my experiences so others who had/will have this procedure can get an idea what's it like. I read a lot about other types of surgery, but since it's different in some aspects, it still leaves me quite blind. I'm taking pictures and everything, so once it's all healed up, I'm going to post the progress with descriptions and so on.
Thus far - as I wrote - there is no sensation at all, the whole area where there used to be the removed tissue is completely numb. They could operate on me again right now and I probably wouldn't feel a thing, hah. But I hope to start regaining some feeling soon, it's uncomfortable to not feel my own body and I don't think I would be able to get used to this. I'm massaging my chest lightly, especially using pressure massage on the scars and sometime the whole operated area, as I read it helps heal the scar tissue.
Interesting fact is, that when I do push ups and blood rushes into my upper body, the operated area doesn't blush or anything, so it's clearly visible where the sensations haven't started yet - this could be helpful for mapping the progress.
