Uneven Results After Radiesse?

I believe that the left side of my face after having Radiesse injections a month ago is still bruised & slightly swollen. But it is hard to tell if it's the product or swelling. Can this swelling last for more than a month?

The actual cheek bone on the left side is tender to the touch and feels puffy so I am assuming it is swelling. All I want is for both sides of my face to look symmetrical. The right side of my face never really swelled so in comparasion to the left side, it appears caved in & deformed.

The left side is healing from the hematoma that developed under my left eye so I am hoping that the puffiness is excess blood under the skin. Is this possible? I just want to look normal and not like a stroke victim. Thanks.
