I went to see my doctor for a sinus infection, and along with prescribed oral antibiotics, he gave me a low dose shot of Kenalog. About three weeks later, I noticed an inch-size white dent in my arm where the shot was given. It is not painful, but looks terrible. I didn't know what it was; I thought I had skin cancer. I remembered the shot and asked my husband, an athlete, and he said he'd heard about it. I Google'd it, and found this site. Nice to know I am not alone! I am going to call my doctor about it. I won't be happy if this lasts forever in such an obvious area.
