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 didnt 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 hasnt 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 - hes out! However, he sleeps then wakes up 3-4 hours later and cant 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. Im just thankful he is alive, but do you think this is a post-concussion or something?
Welcome to Chat Doctor, short answer : he is suffering from post-traumatic stress disorder detailed answer: he needs to have a visit with a psychiatrist. He may need some anti-depressant and mood stabilizers.  Many of these symptoms reduce after a short course of treatment, and you will be advice to continue for a period of time to prevent relapse. Hope this finds useful with regards Chat Doctor.
