Is this possible scar tissue in lip after hyaluronidase? (photos)

5 days ago I had hyaluronidase injected to dissolve juvederm. After the first couple days I was very happy to see my lips took their normal shape again, with a slight deflated look I am sure would fix itself in time. There were bruises but overall everything was great. Now on day 5 I woke up and on my top lip there's a hard area that feels like scar tissue, it showed up overnight, and my top lip is swollen. It's a little sore to the touch if I try to massage it. Will this resolve on its own?
