Soreness 6 Days Post-Radiesse Treatment Normal?

I had Radiesse done in cheekbone area, nasolabial folds and around the mouth and chin areas 6 days ago. I still have some tenderness in an area of the chin that was filled to smooth out some superficial acne scars and textural unevenness. Its not red, but still slightly bumpy and tender. Does this sound like a normal response? All the other areas I had done are no longer sore, just the chin.
