Two weeks ago today, I went to donate plasma at a healthcare center that specializes in plasma. Long story short, they screwed up my arm. It's been bruised and sore ever since - I really hope nothing was permanently damaged.
Does anyone else donate blood / plasma? I'm lucky enough to go to a place that reimburses you for your time - I can make as much as $50 a week doing it. I haven't for the past two, since my arm's been bruised and sore, but I'm looking forward to starting it up again. Nothing like helping people, even if you can't get anything back out of it :)
