MY WIFE HAD KYPHOPLASTRY ON HER BACK 4 WEEKS AGO

MY WIFE HAD KYPHOPLASTRY ON HER BACK 4 WEEKS AGO AND NOW HAS DEVELOPED RED SKIN DISCOLORATIONS ON HER BACK IN THE AREA OF THE BANDAGE. WE APPLIED DESTIN AND LATER CORTIZONE 10 WITH ALOE AND THE SPOTS HAVE NOW GONE DULL RED BUT ARE NOT HEALING. SEEMS LIKE THEY APPEAR TO BE SCAR LIKE TISSUE. ANY HELP WOULD BE APPRECIATED. THANK YOU VERY MUCH
