I am having such a hard time with my PCS today. I am almost 6 mo. in and feel like it will never get better either. My neuro said I would have some bad days - and I thought the days I was having WERE the bad ones - daily headaches, unable to concentrate - then out of nowhere - dizziness, fogginess and just feeling out of it. Everything is an effort. There are no warnings - I try and do everything right - eat well, exercise - it does not make a difference. I read each post and can relate to each symptom. Just a really bad day
