Hello. My 9 year old son is having daily heavy nose bleeds when he melts down. He has these diagnosis' : High functioning ASD (aka Aspergers), ADHD, ODD, PDD, Anxiety, and Insomnia. Daily meds: Risperdal, Adderall, Clonidine, Zyrtec, Fluconasol. When should I worry and what could it be besides allergies? He sees his primary on Monday. Thanks
