Shameless Plug
Don't ordinarily do this, but these Pennsylvania brain injury lawyers really helped a friend in need.
My friend (he asked me not to use his name) was injured when a box was knocked loose from the top shelf by a co-worker and struck him on the head. While he had all the classic symptoms of a brain injury (loss of memory, no concentration, mood swings, etc.), the company doctors refused to diagnose him properly.
After the lawers got involved with their medical experts, the company finally recognized his injuries for what they were and now he is getting the treatment he needs.
Sometimes all it takes is finding the right help. And these guys know their stuff.
