Hi my name is Lorraine, just wish to ask ,,my partne had a metal plate put in his skull after being jumped by somebody years ago. PLEASE help me to understand the long term effects that it will do....as he is a caring and loving man theres a real nasty side as in he way he gets angry and forgets what he,s said. As I love him so much I would be really gratefull if you can help e here in any way. We ride motorbikes BUT hes ok when on road, please HELP. Thank you, Lorraine McMahon.
