question: I was walking about 9 pm and suddenly stepped on a slippery object that moved fast. I lost balance and found myself lying on the pavement. I guess I fell down and probably lost consciousness. I realized the time was already about 1am. I did not suffer and cuts or abrasions on my head. This is the first time it happened to me. It happened last March 30, 2014. As of now I feel fine. I am 58 years old, female. My only medication is for high blood pressure but it has been stable to 130/90 or 130/80. My medicines are Amlodipine Besylate 10 mg and Lisinopril 20mg taken 1 tablets by mouth every day. Is there anything I should worry about? My physician said I should take a Brain CT Scan.
