I suffered a minor head injury 2 days back. Hit my head against a cabinet( wooden) when I got up suddenly from underneath it. Hit the back part of my head pretty hard(or so it felt). It was a distance of 1-2 feet. I am 33 y/o healthy male. No LOC, no confusion, no amnesia of the event or immediately before. I had no symptoms whatso ever for 2 hours. On day-1, I had a mild headache and some lightheadedness. On day-2, for a few hours the headache and lightheadedness (not vertigo) continued. I also had some numbness of Lt leg and weakness of Rt. hand for few hours that spontaneously resolved. After 28 hours, I was completely symptom free. Due to insurance issues and also since at that time I did not feel that my injury was serious, I did not get a formal evaluation or a CT scan done.
However today ( after 48hours of injury) when I was driving my car, I had stopped at a stop light. When I accelerated my car(from stop), due to inertia my head went rapidly forward and back. Immediately I experienced severe lightheadedness for 15-20mins, which slowly resolved. I did work out at the gym( on the treadmill and lifted light weights) afterwards and this did not exacerbate the symptoms. Also I am having some trouble concentrating and at times ( today)finding it difficult to use a few words(no slurring, but unable to recall certain words immediately to use in a speech). Also I find myself a little clumsy and have dropped things twice. I do not know if this is due to anxiety or a true neurological symptom.I have been a trained paramedic and have some medical knowledge.
My questions:
Did I suffer a true concussion? Since I never had any LOC, No confusion, NO amnesia
Do I need imaging studies
How do I manage the lightheadedness?
How long will my symptoms last?
Is Chronic Subdural Hematoma a possibility even though the trauma trivial? head travelled forcefully for 1-2 ft before striking the cabinet
Thanks
