I had a Princess Filler Treatment 4 days ago, What can I do to proceed the healing? (photos)

I had my Princess filler treatment 4 weeks ago. I had to come back to my doctor to have some correction done. He injected in one side of the lip to even out. Now 4 days after my lip is still bruised and have a hard bump, I have not experienced the "bumpiness" before and I have used princess filler for 2-3 years. How long will it take before the bumpiness and swollen goes away? Can I do something to proceed the "healing"? I have not massaged the area+ I bought some arnica gel. /J
