9 days after facial cyst removed: small apricot size hematoma present from swelling. What should I do?

I had a cyst cut out of my jaw line requiring 8 stitches it swelled up and now 9 days later the stitches have been removed and swelling seams to have reduced to a ball behind the scar like hematoma size of small apricot. It is raised up it has only been 9 days since operation. How can i make sure it goes away and how long does it take a hematoma to become a scar lump, Is it to early to heat and massage ? thanks
