I am 50 years old, 5 2 , 95 lbs. I had a cortisone injection 5 years ago to treat hair loss on my scalp. The injection caused an adverse reaction in which a divet or dip was created on my head at the injection site. It was about the size of a golf ball. The doctor said it was a reaction to the injection, and it would heal. It did heal, to a certain degree but was not 100% normal. However, now, five years later, I have discovered not only one diver, but another that are both significantly deep. How did this occur?
