Hello dear, thanks for your question. It is not unusual to have a burning sensation persisting several weeks after liposuction or tummy tuck. During the course of these procedures, the normal sensory nerves are stretched or otherwise traumatized, and during the healing process there is inflammation around the nerves that may create abnormal sensations such as "raw" and "burning" pain, even in response to normal stimuli. These "Dysesthesias" may be worse if ultrasonic liposuction was used during your procedure.But also Skin burns can occur from ultrasonic liposuction or mechanical abrasion. The wand used in for ultrasonic liposuction may get relatively hot enough to burn the skin around the incisions or the skin above the area of fat to be removed.Skin burns can also occur from the constant back and forth movement of the cannula on the skin during the liposuction procedure.These burns usually heal well and do not leave noticeable scars but it may take up to a year to see the final scar maturation.Good luck :)
