Painful,swelling Lumps 11 Days After Juvederm Injection?

There may be a number of reasons for this pain and swelling.  It is possible to reactivate a herpes simplex (cold sore) infection by injecting into the lips, particularly if the swelling and pain is one-sided.  It may also be an infection or a hematoma.  The chances of an allergic reaction to Juvederm are very small, however still possible, and one would expect all the injected places to have a similar reaction.

Presuming that you went to a board certified dermatologist or plastic surgeon, you should have gotten Juvederm itself.  There are unethical injectors who use illegal substances to inject.  Please double check that it was Juvederm.

Please see your injecting physician as soon as possible for a re-evaluation and treatment.

You could be experiencing an area of localized bleeding after juvederm injection, which has developed into a painful deep lump. This is more likely if your injection was around the lip area. It should resolve on its own, and you may apply warm compresses a few times a day for quicker resolution. If the lump, however, is due to too much juvederm injection in the area, your doctor may choose to do an injection of hyaluronidase to dissolve the excess of hyaluronic acid product. I advise that you call your doctor to have a proper evaluation and decide what approach to follow.
