Is my nipple infected?

If you recently underwent Top Surgery,then it is still very soon into your #healing. Therefore, your incisions and #nipples will go through a maturation #process. For the first few months they will be red and possibly raised and/or firm. As the scar matures, after 6-12 months, it becomes soft, pale, flat, and much less noticeable. You may experience numbness, tingling, burning, “crawling”, or other peculiar sensations around the surgical area. This is a result of the #healing of tiny fibers which are trapped in the incision site.Being your doctor did not voice concern, it may be best to contact she or he and inquire further. It is possible you may need to apply a topical #healing #ointment per their permission. However, it's best to confirm such beforehand and the type best suitable for you. 

This is not infected.  This is one of the possible loos of a full thickness nipple graft.  The local wound care will be enough to get the healing accomplished.

This does not appear to be infected. Continue with the wound care prescribed by your surgeon and you should be fin!
