My 9 year old son, who has ADHD, cannot stop picking at the skin around his nails. It's a compulsion like nail biting. It truly is a compulsion and he cannot stop. I've seen his doctor and he has no ideas I have not tried. I'm almost at the point where I will have to leave his fingers bandaged in the evening so he'll leave them alone, and I feel that's really extreme. I would not do it at school although the majority of it goes on there. The teachers are trying to help, but to no avail. He wants to stop... it breaks my heart. I am sorry if this subject is a bit graphic. I just need help. We assume it's the Adderrall... this started about 4 mos after he started it, maybe less.
