Hi, I need help determining whether or not I had a concussion. I had a CT scan last week, which was fine, with 2 opinions. Concussions don t show on CT scans though. I stepped backwards to turn, and swung my head to meet with a solid metal bar, and it made a loud noise. I do not remember any immediate signs of concussion; I blanked out for only a second, not enough to lose my feet. Don t remember anything before or after the incident. I think I was having fevers, I vaguely remember dizziness , and only one headache, although I think that was some time afterwards. I m worried about delayed symptoms however. I ve been in a huge daze for the past 10 weeks, since the incident and a G/A a week before, feel like I haven t woken up from something, poor concentration, mental dullness, concrete thinking, DP and DR, anxiety, panic attacks, depression , lethargy , fatigue, feeling detatched from reality, personality changes, never feel properly awake. I was working my way up to distinctions at university, and now I cannot begin a simple essay. I just feel tired and different, No creativity, I m apathetic, emotionally numb, disorganized thinking, and bad forgetfulness, feeling disoriented and dissociated. Insomnia at times, seeing stars, blurred vision , and sensitivity to noise. I don t feel as bright or capable as I did before, and a lowered IQ, less insightful. I know my symptoms are probably psychological, but I m aware enough to know that concussion could possibly have lead to them. I m 19, 49KG, female. I just want to rule out concussion, and if so, Post Concussion Syndrome. Thank you.
