My 4 year old son complains of headaches quite a bit and I thought it was cause of his Intuniv. Tonight he said his head hurt and pointed where it hurts and he usually don t do that. He just finished a round of Cephalexin and is still coughing and having runny nose too. The area where he said his head hurts is the bone right behind his right ear. It s the whole bone, when looking at both sides, you can tell the right side sticks out more.
