Nerve pain after Lipo and BBL?

Hello, I am now 4 weeks post of op of liposuction on my back, flanks, abdomen and fat transfer to buttocks. I've had nerve pain in my right foot and calf, my doctor says its from the inflammation caused by liposuction and once the swelling goes down the pain will disappear. Is this true/common? This pain can be excruciating, especially at the end of the day. For my own peace of mind I went and had an ultrasound done to rule out blood clots (no blood clots where found)
