Hematoma?

I got a pretty big hematoma from my lx. At first, there was a question of infection (like cellulitis) vs hematoma. A nurse marked it with sharpie to see if it spread, which it didn't. The tissue actually got a bit hard as the blood was reabsorbed, and the skin tone never really went back to normal (it stayed darker, like scar tissue). Most of it was taken when I had my mx, but a tiny bit of it remains to this day - 14 years later. I'd follow up with your team, though, as infection should be ruled out (or treated).
