Yes -- my son is exactly the same way. He's six now, and has been diagnosed as ADHD, which is well controlled with medication (Concerta), and ODD, which there are behavioral interventions for. We recently started him on Tenex, which is an anti-hypertensive drug, to control the rages, so far it's been working well. Otherwise he flies off the handle several times a week at school and has already gotten detention twice -- and he's in first grade!
Our son was evaluated/diagnosed at around 4 years of age, but we didn't start medicating until a year ago. I am so glad we did. Nothing we did seemed to help his behavior.
I would strongly urge you to have your son evaluated -- your ped can get you a referral. Good luck!
