I got revitari velvet hyaluronic acid butt filler injected in my butt throughout the year however the last time I went, I developed a lump / hard on right side of my butt. I recently got Hyaluronidase dissolved however I still feel like lump.. now I’m worried this could be something serious. Why did this happen? Do I need to be injected with more Hyaluronidase ? Do I need cortison shots? Can this surgically removed? Should I use a massage gun?
