I would see a psychiatrist to find out if there is a serious problem. My anger pops up out of nowhere and goes from 0-60 in a millisecond and interferes very much with my thought process. The sight of someone or something can bring up anger in me (which I could never explain). And when I'm angry all of the issues I've had in the past with relationships floods my mind and are intrusive. Quick anger can be a defense mechanism and/or tied to other issues like trauma. I would talk to someone about it.
