2 years post Juvederm - will the bump on my vermillion border go away on its own or should I have it dissolved? (photos)

Hi!I got juvederm lip filler 2+ years ago and went to a “reputable” plastic surgeon. surgeon. He made a bunch of injections along my vermillion border as his technique. Once the swelling went down a few days later, I noticed this one little bump/blister that has since not gone away. It looks terrible, especially with lipstick on. I went back to him and he said to see if it goes away on its own.It’s been years,will it really resolve on its own or do I need it dissolved/is it scar tissue? Thanks!
