Healing after gyne surgery can take up to six months on average -- less in some very young and healthy guys and longer in others (I have seen healing up to a year or more).
Healing is more than the absence of a bruise or minimal/absent swelling. Healing continues under the skin and it is dictated by Mother Nature. Neither the patient nor the surgeon have much influence over the natural healing processes. Sometimes everything heals smoothly and the result is a fantastic looking chest with smooth contours, flat areolas and minimal scars. Other times, there may be a buildup of scar tissue, or the scars may be prominent or there may be prolonged firmness or decreased sensation. There may also be minor twinges, tweaks, pulls, etc -- which come and go until they gradually fade away -- permanently. All of these tend to settle down over time -- but one must be patient.
I usually tell my patients that they can return to full activity at about one month after surgery -- but that there is continued, slow healing under the skin. It will take many months for everything to soften, for the skin to move naturally over the underlying muscle, for the scars to become virtually un-noticeable and for full sensation to return to the skin and nipples. This process is very very slow -- it just kind of sneaks up on you until one day you can touch your chest, look at it and say that it looks and feels totally natural and as if no surgery had ever been performed. THAT is full healing.
