Teeny Tiny Vampires

I just got up and helped my roommate, who is putting together some bookshelves. My job was to apply counter-pressure for her as she drilled in screws. And I had another symptom that I don't think I've shared. Maybe I mentioned it before, but it's happening more often.

When I use my arms, I feel like they don't have any blood in them. You know the feeling you get when you raise your hand for a long time? Or lean over a chair with your arms in front of it? Or rest your arm out over the movie theater seat next to you? That's what it feels like. I think raising your hand and leaving it up is the best parallel for this feeling. It's like the blood drains out and it begins to get numb.

Wait, numb? Oh, brother. More numbness. But this is different than what happens with my legs, because there are no pins and needles. And it's a weaker feeling. Also, I don't notice it until I go to move my arms; the pins and needles are apparent at rest and during use.

My best guess is that teeny tiny vampires have moved in to my arms and are slowing draining my blood.
