Yes take him in to see Ped and get the fastest referral to psych you can, they generally take a while which is why I wouldnt wait. My 8 yr old (7 at the time) started last fall only his was constant all day long and barely slept. I won't go into details but got real bad. Support for him through counseling to work on the root of problem and meds if warranted are needed as well as support for the whole family.
Pm me if you ever want to talk and good luck to your son.
