Since you still have many unanswered questions about the procedure you are apparently sheduled for, and its aftermath, I would suggest you schedule another appt. with your plastic surgeon, who would be the best source of the information you are seeking.
Just to add my 2 cents worth ..... IF you have that many questions you should either ASK at another appointment with your current Plastic Surgeon OR cancel your procedure and seek a second opinon from another Plastic Surgeon. To get the answers we need regarding any type of health care ... we need to ASK the Dr. when they are in the room ... write them down at home if you need to and read them off from the notes you make. You should NEVER undergo any procedure until you understand completely everything about the procedure itself and what to expect during the post-op period. Best wishes for a successful reconstruction, whatever you decide.
