Can Ultherapy cause lymph nodes to swell?

Although localized lymph node swelling isn't a
typical response, it's definitely possible. The swelling you describe is likely
related to your recent Ultherapy. However, if the swelling persists for more
than an additional week, or if you begin to develop other symptoms such as a
fever or fatigue, see your primary care physician.

Ultherapy can cause localized swelling in the area of treatment. The body may respond with some areas of lymphadenopathy. If the swollen lymph nodes don't go away quickly, I would speak to your primary doctor about other causes. Best, Dr. Karamanoukian Los Angeles

Yes this can happen after ultherapy, diuretics, steroids and NSAIDS can help.  However, I would suggest waiting a few weeks for this to resolve.  Best, Dr. Emer.

You do get swelling from ultherapy. I would go visit your doctor to see exactly what is going on. See exactly what your doctor says

Yes- Ultherapy causes inflammation below the skin's surface and the clean up mechanism involves the lymph nodes.  Generally, this condition should resolve within a few months... but don't ignore it.  Since other conditions- like cancer- can cause swollen nodes as well.  be sure to have your doctor follow you along and keep an eye on this condition.Hope this helps!
