I had a blackout Wed. a week ago and fell head first going up the stairs of the metro station in Paris,(was not on the menu), hit my hesd, hurt my knees and ribcage and ended up in the hospital it was the second time in 6 months that i lost sudden consciosness & fell forward just to come to myself when hitting the floor. in this case the concrete. Had 6 stitches on the forehead, very fashenable in Paris.... My doctor here in sfo put me on a heart monitor for the rest of the month....I take Atenolol, 025mg for a long time. Should i ask for a Brain Scan to see if this was due a stroke??? thanks you
