I found the first 7 minutes after it was initially attached and started to suction my fat to be excruciating and fought the urge to rip the machine off me. It pinches, feels very cold, heavy while you're laying down and in general entirely uncomfortable. But there is a light at the end of the tunnel when you begin to numb and it does become tolerable. But I had to cough once during the 30 minute mark of my first lower abdomen section and it hurt A LOT! So do not move once you're hooked up to it. When it was removed I couldn't feel anything at first until I was massaged and thawed out a bit. It feels similar to the worst menstrual cramps for about 6-8 minutes as I thawed, it was suggested to help get through that pain to lay across the bed on my stomach as the pressure would help and it did.
I have a lot of swelling, look like I gained about 15 lbs or more right now as well as some spotted purple bruising around my upper abdomen part. I am 4 days in and feel some deep itching, tingling, soreness, swelling, numbness and general discomfort when bending or being in bumpy car rides.
What I will say though, if this works as well for me as some of the best after photos then I would go back for another treatment even with all the discomfort. I will keep this updated with lots of photos as I go along an attach the ones soon from the office I had it done at the day of.
