What you are describing is very unusual. Juvederm typically lasts 6-9 months tops and can be reversed with hyaluronidase injections. I would suggest that you book a consultation with a board certified plastic surgeon or cosmetic dermatologist in your area (link below) who has extensive experience with fillers to discuss your unique issues. I am so sorry that you are experiencing this. Best, Dr. Nazarian
Typically Juvederm is a temporary filler and lasts 6-9 months. It can also be dissolved with hyaluronidase. This sounds like a very unusual reaction to Juvederm. Permanent nodules are typically not seen with temporary HA fillers and are usually only seen in the permanent fillers. I would return to the injector who injected the areas for an assessment or see a board certified dermatologist of plastic surgeon experienced with dermal fillers for a thorough evaluation of the areas.
I would definitely consult a board certified dermatologist to have Vitrase injected in to that area. Pleas post a photo so that we can see the area involved. Best, Dr. Green
