I had tickle lipo done on my flank,abs and back 6 weeks ago with no results. I experienced a great deal of pain during the procedure, and to this date I have not seen a single change in those areas. My doctor offered to redo the liposuction at no cost. I don't think I can handle the pain this time, would IV sedation increase the risk of liposuction complications ? is it more safe to do it with out sedation?
