I have an 8 year old boy diagnosed with adhd, recently he has been hurting/ injuring himself when reprimanded, he hits himself on the wall/bites his inner lip and scratches/pintches his genatalia.

Psychological eval: Recommend that he be seen by a child psychologist for a work up.

Needs eval: I agree with DR Fowler. ADHD kids or kids in general who self harm do so when they cannot handle the stresses their situation brings them. A therapist can help the kid explore their feelings and learn non hurtful ways to deal with their frustration. The skill set needed to do this are not acquired automatically in life experience.A skillful therapist can help the kid learn & get past these issues

Cry for help: It's often difficult for children with specific disorders to cope with their special circumstances, let alone the stress of growing up. Please, he needs more than an accurate diagnosis. He needs appropriate therapy and/or medication. Please seek care from a Child Psychiatrist for best adaptation.
