How long before the bumps that look like blisters on my lips disappear after Restyln injections

I had Juviderm injected into my lip lines and directly into my lips. One week later and I have a blister on each side where he injected the lips. How long before it goes away. I am still a little purple on one side of my lip, it was so worth it. The lip lines are so much softer, he went right into each line and ended up with a shot on each side of my lips top and bottom, 2 viles. The pain wasn;t so bad, we iced it before each shot to numb the area and it worked
