Can't rotate my left palm to face up since birth! Becoming very annoying.?

[Jon R]

I am a 23 yr old male and this condition affects my left arm. I was never able to touch my shoulder with that hand. Also when I am given change from a drive through window the change will likely fall out of my hand unless I want to point my elbow in real far to flatten out my palm. Which looks very strange. I also believe that this is why my wrists and forearms are so skinny. The rest of my body is of regular size for my age but I was never able to work out my arms much because my left one can never keep up with my right one when I bench press and stuff. It will start to tingle like there is some sort of nerve damage. My mom told me when I was born I got stuck inside of her for a little bit I don't know if that had anything to do with it. I really need to find some information on this nothing much on the net and this is a very frustrating condition. I can also not play a guitar because of this unless the guitar is in an akward looking vertical position due to not being able to wrap my hand around the neck of it. I can't face my palm up at all with that arm and if I try to help it with my other hand the bones wont allow it to turn any more.
