Its always wise to stick to the instructions that your surgeon gave you. There are so many different ways to do the surgery and your surgeon knows what he or she did and how to care for it. Be careful of any medications, even over the counter post op and check with your surgeon if you think you want to try something.
I don't know how common this is, but I had numb areas around the aereola for a long time. To this day, one side has a strange itch that appears occasionally from deep inside the tissue.
It also took a while for my nipples to respond to stimuli again. Be patient.
On the light side, for about six months post op, after the incisions had healed, every now and then a piece of internal suture would migrate out of the tissue. It never caused any problems, it was just kind of weird.
