Swelling all over face after dissolving lip filler

Hi all

Long story short - I was overdosed with hyaluronidise to dissolve lip filler I only had for less than 3 months. The injector injected a lot of hyaluronidise around my mouth claiming the filler has spread. That was 7 weeks ago and I’m still battling persistent swelling throughout my whole face, even my under eyes are swollen. It goes down a bit during the day and it’s mostly visible in the morning. I also have lax skin and my lips are a lot smaller than my natural lips and pulling down.

Has anyone experienced this and recovered? What can I do to get better?
