Received revision cheek implants this morning. I got a sudden painful/firm swelling only on my left side.

I had very small malar cheek implants replaced w larger ones this morning. I was fine until the evening when the left side suddenly became extremely swollen. I know it very normal for this early on. But it feels very painful and I don't remember pain like this when I got the small ones. Also, it's very firm and putting uncomfortable pressure on my teeth. Is this normal swelling or signs of an infection/hematoma.
