I have a granuloma in my lip appearing after 6-24 months of filler injection. I tried hyaluronidase to dissolve it and it won't go away. Does it go away by itself after a certain period of time since I do not want to go to an excision procedure? My doctor tried fluorouracil 2 days ago and the results aren't shown yet, how much time does it need for fluorouracil to take its effect in the granuloma. Thank you .
