Dark Nipple After Gynecomastia and Areola Reduction Surgery?

I had gynecomastia and an areola reduction surgery 5 days ago. I feel fine with little pain and discomfort, but one of my nipples (right side) is much, much darker than the other. Both of them are seemingly numb, but the ride nipple is almost purple.What is the cause of this? Loss of blood circulation or due to the sutures? Is this a "dead nipple" and will I lose my nipple or need reconstruction? I just want to know if this is normal or something that I should be concerned about. Very disturbing and worried.Updated Feb. 24, 2010:As requested, here is a picture of the nipple I mentioned in my previous question. I did see my PS today and he said that it "should be just fine", and that it looked like it was "vascular (or venous) congestion" in the nipple. Is there anything I can do to uncongest this or get color to return to normal as soon as possible (like my left nipple). Any help, advice, or expertise is much appreciated. On the phone the other day he did say that it looked like I had good blood flow after the surgery/sutures
