1 month pimples and stubborn grafts

[Londinium]

I've been getting pimples (well, just two) since a month out from my transplant procedure. They have largely cleared up and the pinkness is beginning to disappear (I'm on day 45) and am just wondering if the pimples are a sign of early growth or something else. I also have a few hairs still hanging around but I can't tell if they have grown or not as the transplant was onto the back of my head and obviously I don't have eyes on the back of my head. My roommate claims they've been growing but he said these were the hairs along the edges of the scar that I had the hairs transplanted into (the recipient area). This could either mean merely returning donor hair or continual growth of hair grafts but honestly I can't tell because as I said before I can hardly tell what's going on back there without somebody else looking at it. I'm HOPING it is early growth because my biggest worry is that my scar doesn't have sufficient blood supply for the hair grafts, a fact that my surgeon brought up a few times both pre-op and post-op. Anyway, I'd just like to know what's up with these early pimples and stubborn grafts that haven't fallen out yet. Thanks.
