You asked fairly specific things, and you have been through serious surgery. Many people won't post about things they have no experience with, and few if any of us are doctors. Even if we were doctors, without first hand knowledge of the particulars of your condition, most still wouldn't comment.
I hope you stay on the forum, your experiences can help others, so that the next person with similar experiences, you can say that "in your experience, this is what happened". The forum is also wonderfully moderated. It would be far better that no one responded to your situation and caused no harm, than to have someone reassure you and have something go wrong. I can understand your feelings, but have seen many people extend themselves to others. But of course not everyone receives many responses, it's not you, or the other people, it's the question and ability for others to answer it.
