I had a severe fall and as a result, a head injury. I went to the ER by ambulance. I didn t remember anything until I was in the bright room with nurses and doctors, lying on a stretcher. This was three days ago. I have a headache, slow memory trouble, sensitive to light, ringing in my ears ,maybe some trouble with balance, no appetite, etc. I had CT scans and EKG testing; all normal, yet I m wondering if I should see a doctor now. Please answer if you can. Thank you.
