My husband was in a single vehicle accident on Friday. His truck flipped 3 times and rode the guard rail backwards, upside down. We are thanking God that he didn't get hurt. He got out and felt ok. There was a a couple nicks on the back of his head (they thinkfrom the glass) and a small bump appeared. Paramedics checked him out and he refused to go to hosp because he felt he was ok. A miracle truly! He also went to Urgent care on way home and they also checked him over and said he was ok, to keep watch for the next 48 hrs, perscribing pain medn if needed. He hasn't been sore, no muscle aches nothing. However, what I am noticing is he has become more aggressive and almost obnoxious at times, he gets irritated easily and his sleep has definitely been disturbed. When he sleeps - he's out! However, he sleeps then wakes up 3-4 hours later and can't go back to sleep so gets up. He also said today he has been experiencing nightmares (he never has them) and also prior experiences in his life have been part of these dreams. He was already a very determined person, but seems to be more so in everything he is doing. The accident happened on Fri. His truck was totalled. I'm just thankful he is alive, but do you think this is a post-concussion or something?
