My son sustained a concussion after one of his co workers came up behind him and goosed him. He reacted by jumping straight up and hitting this kid in the nose breaking it. The place where they worked didn t even call the paramedics. They had to seek medical help after they re shift. Anyway it s been some time since it happened and I ve noticed some behavioral changes in him that are good. My son was diagnosed with a concussion and they just turned him loose. My question is: Will this thing just heal on it s own or what. He has had some character changes since this happened. He is harder to get a long with and gets almost violent. Anything you can give me help with? Peggy Harris
