Hurt like hell, even with the numbing cream, doctor went in about three times for a large indented chin scar. It is still rock hard, I'm concerned with the lump like appearence, how long should it last?I had a Radiesse injection this afternoon for a indented scar on my chin. It has been approximately four hours & the area is hard as a rock, feels like a giant cyst under my skin. Is this normal? Should it subside soon? Please help, I'm extremely worried..
