Swelling feels hot after juvederm ultra plus. Could this be a sign of an infection?

I got juvederm ultra plus in the back of both of my cheeks for volume loss and radiesse around my mouth yesterday. The injections were done by an experienced dr. My right cheek and the area around my mouth feel fine. However, I got a somewhat larger bruise on my left cheek which got very swollen. Even parts of my temple area (which was NOT treated) are swollen. I understand that some swelling is normal but my concern is that it feels really hot. Could this be a sign of an infection?
