Laser hair removal on chest 1.5 weeks after gynecomastia surgery (Lipo only)

I had gynecomastia surgery 2 weeks ago (lipo only, no gland was removed), and healing had been great. I then had laser hair removal on my chest a 3 of days ago, and since then have noticed that a small area next to my right nipple has hardened/swollen, which I am sure is a consequence of the laser removal on the area. There is no change in colour (ie - doesn't appear to be purple or black). Can someone explain what happened and whether this is something that will go away on its own? Thank you!
