I had a lower neck/face lift on 30Jun16. 7 to 10 days ago, behind my lower right ear at the incision line tenderness and swelling began and continue to build until last evening. When I look at it now, it is very swollen, purple and strange. My question is this, can a hematoma from this surgery develop this late in the game? I do have photos. Thank you in advance for any response, Christien
