I can't really offer much help, but I remember ds being like that at times. He also had late verbal development and I wonder if that might be part of the issue. My son will now occasionally scream that insane ear-shattering scream, but now he understands when we tell him not to do that...if he is going to scream, please do it in a different pitch so it doesn't make our heads explode. :LOL He is slowly learning to control it as he slowly gains verbally.
I have also had to stop him from the 'lets slam our head / body into the wall and scream because it hurts' behavior. I can't tell you exactly what helped, but either something did or he just outgrew it. I don't think it was one specific thing that helped...sometimes holding him helped, sometimes it made him crazier...same with distractions, finding something else to slam into like jumping/falling on our king size mattress (on the floor), showing him to bang his frustrations out on drums/rattles/shakers, having him draw his frustration, putting him in the tub where he could splash...and a million other 'find another way to express frustration' type things.
Mine is 3.5 now and we really don't see the behaviors very often at all any more. I know it is insane. My brother actually gave me earplugs and I found a pair of noise deafening ear protectors (for hunters...in the gun section at a sporting goods store) for when I had a bad headache and just couldn't take it any more. I felt idiotic, but I was just out of ideas and patience and didn't want to go postal on my son.
I hope other mamas have better suggestions. Waiting to outgrow a behavior has got to be the most frustrating advice ever.
