Kenalog and kno

i received a kenalog shot about 5 months ago on just one single pimple on my left cheek. about 3 or 4 weeks after the shot i got this huge indentation and discoloration. mind you the rest of my skin is completely clear with no acne nor scars nothing so this indentation stands out even more. the discoloration went away completely and the indentation filled some but not all the way. i went to 5 different dermatologists and all say the same thing that it will eventually fill in on its own as the skin regenerates itself in close to 2 years. the dr who gave me the shot gave me no warnings and now im stuck with this unsightly dent in the middle of my face which apparently will correct itself. i have gotten all the fillers like restalyne and collagen but it doesnt work all it does is push the dent to the surface of the skin and its obsorbed in about 2-3 months anyway. if any one has had this experience before particularly on the face please tell me there is hope that my skin will go back to the way it was before or if you kno of any sort of treatment please let me know.
