Oxman,
Well done. I have been informed by a surgeon friend that the hard areas can simply be as a result of having worn such a tight bandage for a week or so - are the ridges coinciding with where the bandages lay? If so, he has said some simple massage in time will get rid of that. And for the nips, well if gland was removed, I guess there is nothing there now, hence the dent.
My view is that for 1 week we prevent our bodies from really repairing the damage by dressing the area so tightly, there is no tissue movement. Now the bandages are off, I am sure you will start to see you body work it's way through the mother of all snagging lists!
