Should You Sleep Sitting Up for a Day or Two After Lipo on Chin and Arms?

Elevating your head (higher than your heart)  after liposuction to the neck using an incline (not necessarily sitting up) will decrease swelling and speed healing

The most important components of chin and neck liposuction recovery include wound care, compression, and massage.  I would try to get a good night's sleep and optimize your health during recovery. Good luck!

I do not think that it is neccessary to sleep sitting up after this procedure although it is a good idea to sleep at an incline with a few pillows behind your head. This will help with swelling. You may also want to have a couple of pillows to rest your arms on.
