I had my Liposonix treatment just the other day. The procedure was very easy. I had my lower abdomen (pooch) and my love handles treated. Dr. Lee treated each area with a series "pulses". She offered pain meds before the procedure but I decided not to have them. I could see why some people would want them but I personally found the procedure very tolerable.
Each pulse feels like a prolonged electrical charge with some spiking of the current and movement of the charge in each area. After the procedure I had some tenderness to the treated areas which also was slightly warm to the touch. I was able to immediately resume normal activities.
The next day some slight bruising appeared in the treated areas. It is too soon to see the results - I was told it would be 8-12 weeks before the final results could be seen. I'll update then.
