Sudden increase in pain two weeks after liposuction - is this normal?

I had liposuction on my abdomen two weeks ago. Yesterday I had my second ultrasound massage. Previously, the pain was decreasing, but it has increased twofold after the ultrasound. Not only the muscular pain increased, but also the skin has become extremely sensitive tingly) to anything touching it. What could be the problem? I will be talking to my doctor tomorrow, but would like to hear whether such a sudden increase in pain can happen after two weeks.
