They don't bother me either.
I'm fine, my doc referred me last week for a blood test for a problem that I've finally decided I've had enough of, secretly I think she wanted the blood test done anyway because she's convinced I'm anaemic. I'm not entirely sure what they were planning on finding with a blood test since I'm not sure what that has to do with the problem I've got, but never mind.
The time before I was fine as well. My brother wasn't so happy, they spent 5 minutes poking around in his arm for a vein, he was a mess afterwards.
Well whatever is going on at least it's good to know you're fine. Your brothers luck on the other hand could use some work.
