Neck Still Partially Numb One Week After Lipo?

After liposuction, it is typical to have areas of numbness for several weeks.  Most likely the numbness will resolve over the next few months.  In addition, the weakness of your lip is common after liposuction is performed under the chin.  This can also last a few weeks to a few months.  While nerve injury is possible, it is likely that the numbness and weakness will go away.  I would not be worried one week after your procedure. 

It is not unusual for the neck to feel numb in areas for several weeks after liposuction.  The nerves are not severed, but they can be bruised by the procedure and take a few weeks to fully recover.
