Questions: how painful is liposuction or how painful is liposuction under local anesthesia can really bother patients. Yet, the truth is, liposuction surgery is not painful at all. Thanks to general anaesthesia or local anesthesia liposuction, patients do not feel any pain during the procedure. With general anaesthesia, patients are put asleep. With local anaesthesia, operated area is numbed, so again no pain is felt. However, patients should realize that they will feel pain after the surgery. They will need to take pain killers, a surgeon will also prescribe some strong after surgery pain killers to alleviate the post-op pain.
