3 weeks post op Vaser Lipo, I have lumps and swelling. Is this normal?

You can have swelling and irregularities post liposuction up to 3-6 months.  I suggest starting massage, ultrasound and/or radiofrequency (Velashape) to give improvement.  Best, Dr. Emer.

The #lumps may be diminish with time and self-massage may help. If not, your doctor can provide suggestions for this concern. In-office medi-spa treatments may be an option. But, it's best to be patient in the meantime. Swelling after #Vaser liposuction is not uncommon. Gentle #walking may increase circulation and help to alleviate swelling. But you must not strain or push yourself. Also, if you were provided a post-procedure #garment, be sure you are wearing it until prescribed otherwise by your doctor. The purpose of the post-procedure #garment is to provide some gentle #support and to reduce swelling. If it feels too tight or causes pain, take it off. Many patients wear the #elastic garment for several weeks after procedures, as directed by their doctor; some choose to wear it longer for several months for comfort.
The final results of the procedure are typically most noticeable 2-4 months following the #Vaser. So, you must have patience. The swelling will gradually diminish while the contours of the treated area(s) can continue to improve up to one year post procedure; becoming more apparent in appearance. If you have concerns about your healing, or pain that you question to be unusual, it is important to call your plastic surgeon to discuss these further asked to be examined. 

Three weeks out, it is early to say what your end result will be. Swelling resolves over 6 weeks or longer. The hard lumps will resolve most of the time. I use the VASER extensively in my body contouring practice, and although hard lumps can happen, it is rare if the area was treated with a good technique. Follow up with your plastic surgeon, there's a possibility that additional surgery might be needed if these don't disappear in 6 months. Good luck.
