I had lipo 360 on arms 20 days ago and i am still in a lot of pain! Is it normal to be in this much pain after liposuction?

Dear viviansoto33,you shouldn't have any severe pain 20 days after liposuction. I would suggest you to consult your plastic surgeon. You will get the best recommendations after a thorough examination.Daniel Barrett, MD, MHA, MS

Pain can be variable for patients who have had liposuction. If necessary, this pain can be treated with anti-inflammatory medications and neurontin. You may still have some swelling, which may last 3-6 months after your procedure. I recommend adding hyperbaric oxygen and lymphatic massage along with your compression to help decrease any swelling. To improve your final results, I also recommend adding vanquish for further fat removal, exilis/venus legacy for skin tightening, cellutone/z wave to make the skin smooth, remove scar tissue, and improve the skin’s appearance. See an expert. Best, Dr. Emer

I am sorry to hear that you are still in pain.  Most patients are settling down by now.  See your PS for evaluation.  Some medicines may take the edge off.  I think that you have seen the worst days.  

Typically patient will have pain or significant tenderness for the first couple of days.After that patient often describe the feeling is having overdone it in the gym when being out of shape.Having significant pain three weeks after the procedure is unusual.Patients receive postoperative discomfort differently and the level of aggressiveness of how the procedure was done will change how long patients having afterwards.Typical areas that tend to have lingering pain or the front of the abdomen and over the spine as well as over the ribs when these areas were treated.Circumferential liposuction of the arms and sometimes results in the cannula hitting the muscle or the covering of the muscle called the faciia.With enough time the discomfort should fade completely.BestMats Hagstrom, MD
