hi-hope someone can help me with this-my 3 yr old nephew got sick and went to the doc and got a shot-well where he had the shot in his hip it has left like a hole-i really don't know how to describe it-his mother worries herself to death over this-anyway the doc said something about fatty tissue or muscle or something-sorry this isn't very clear but i'm getting it second hand-has anyone heard of this or had this happen to someone you know-thanks
