I had both sides done and attempted to have my lower abs done. Trying to lose stubborn pregnancy fat! The procedure on both my sides was very uncomfortable, but you get use to it after 10 minutes. They attempted to do my lower abdomen and it did not go well. They used 1 large suction device and the pain was excruciating. Two minutes into it I passed out and the device was removed. 1 week later I still have bad bruising on both sides and even some in the front. My sides are sore and hard. Hoping to see results soon!
