My daughter scratches a lot to a point it breaks the skin til it bleeds. I don t know what is causing her to do this. She hides to scratch because she knows I will say something to her. It is mostly on her exposed skin. It is on the bottom of her legs and her arms mostly. I think it is a reaction to being biten by misquitos. What could it be and how can I treat this. I don t want this to scar her skin for life she is such a beautiful young lady I don t want this to affect her in the long run. She is almost 11 years old. I have tried cortisone, hydrocortisone ,Neosporin, lotions for itching etc. She has been to a dermatologist and they were no help. She said it could be a stress thing and to keep doing what I m doing. I have never heard of this stress thing what does this mean? Can you please help or suggest something that could. thank you
