Could this be hematoma or normal healing 3 days post submentoplasty and liposuction? (Photos)

I am 3 days post op from a submentoplasty and neck sculpting liposuction. I have a drain on the right side of my neck, but the left side seems to have significant more swelling. There is more bruising on this side as well. There is a mass when I touch the spot. The on-call surgical fellow says it’s impossible to have a hematoma with a drain, but I have my suspicions and will be following up with my surgeon in the morning. Any additional advice would be most appreciated.
