Hello, Tonight I hit my finger and the blood flow stopped at the top of my finger. I have always been afraid of blood but have never been unconscious. I just get a bit nauseated or dizzy. After using a sterilized needle to let the blood out, I only felt nauseated. After about two minutes, I felt sick, my ears were ringing, my hands were numb and I fell on the floor unconscious. My sister was with me, trying to wake me up. She says while I was unconscious, I also wasn t breathing. My breathing stopped for about less a minute or so. I ve read that being unconscious after seeing blood is normal but the breathing part is what I am concerned about. Please help.
