I received an injection to my eye from my doctor. I felt no pain from this. After about 10 minutes, my eye bled a little and I started to feel weak and passed out. I have fainted many times in my life usually from the sight of blood although I try to fight it.

While sleeping, and changing positions, I will experience vertigo. It soon passes, but happens quite frequently. Once, having to get up, during the night, dizziness was quite extreme. I took one step, and immediately blacked out, and collapsed on floor. This was not long in duration and I soon became conscious, however the condition exists. After sitting up, I must wait for the dizziness (vertigo)to pass before taking a step, for fear of collapsing again.

I've had two episodes of fainting. Once in the summer, and once last night around 2:30AM. It happens once I get out of bed, either walking or standing. Last night I was taking my dogs outside, my ears had the wave sounds and I had to lie on the grass to keep from falling. I managed to get into the house and then I just lay on the floor. I had been packing up stuff to move, up and down stairs, and my legs had bad cramps so I had put heat on my legs before all this happened. The time before I had sonograms on the carotid veins and my heart, nothing was found.

The last thing I remember I was sitting at my computer playing a card game. I started to have a strange dream, almost like I was high on drugs (pleasant and without any pain). My wife came in the room and found me out cold with my head on the computer key board. As soon as she woke me I felt fine.
