How long should the numbness/tingling stick around after liposuction?

At one
week you are likely still experiencing a lot of swelling. There are no hard and
fast rules for Smart Lipo, as every patients body reacts differently. Some
patients see results immediately while it can take time for others. I typically
tell my patients that will see a difference by the 4-6 weeks mark. It can
sometimes take as long as 3 months to see the final results.

Typically the first 6 weeks are the worst.  There is a combination of swelling and bruising that contributes to this problem.  Continue to wear compression and follow your doctors advice.

First and foremost, the sensation almost always returns to normal.  The abnormal feelings are the result of a combination of destroyed superficial cutaneous nerves and swelling in the tissues (soft tissues and superficial nerves).Nearly without exception, these odd sensations do resolve, although it is possible for it to take up to 18 months to occur.  The faster the edema goes away and the quicker the nerves re-establish their connections, the quicker you'll see things improve.Hopefully you went to a board certified plastic surgeon who can advise you on the best maneuvers to help improve the swelling; beyond that, it is just a waiting game.
