I was 14 and had to have blood taken twice a few months prior to surgery I was going to have.

The first time went smoothly.

The second time....well... they took the blood and I remember leaning my head against the wall. Then I felt fuzzy.

When I woke up I was on the floor and I felt nauseous.

I had had a seizure.

Ever since then, I have to lay flat when getting an IV or giving blood because I'll pass out.

Haven't had a seizure since though.

Even so, I'm not a big fan of needles because of what had happened.
