I too had a head injury a few years ago and because of all the other physical injurys my brain was the last on the list to get looked at. Money is a factor by the way for us. I have to get tested next week by a neuropsycologist for short term memory. I am going to bring up your PCS. I have exactly the same issues. I was ran over by a car and was knocked out. It was a hit and run. I finally gave up and have filed for disability due to not working for the last 2 1-2 years. With 19 other injurys my brain is still not right. No one has ever said PCS to me....glad I seen your post.
