The right side after Ultherapy has pain, swollen, & numbness. Is this a nerve damage? Will the collagen grow asymmetrically?

The numbness you are experiencing is most likely related to a nerve and will subside on its own, though it may take a little bit of time. Swelling will also decrease by itself, but it requires patience. 

Hi Shannon,Sorry to here about your side effects of Ultherapy.  Fortunately with over 300,000 worldwide Ulthera treatments over the past 5 years I have not heard of any permanent complications.  The longest that any side effect from Ultherapy has lasted has been about 3 to 4 weeks.  Your swelling is not nerve damage.  Sometimes if local anesthesia is injected there is more swelling.  Your numbness is related to your nerve and should resolve within a few weeks.  Your face should ultimately be symmetric.  Be patient and speak with your treating physician.  Good luck and be well.Dr. P

During Ultherapy, any patient who complains of pain in the treated areas like over the jaws should prompt the treating physician to lower energy levels transmitted by the transducer. If the provider continued 'through the discomfort', don't worry, the discomfort, pain and numbness should go away - it may take up to 8 weeks.
