Wow! Donating double red blood cells is not for me. It's been four days and I'm still tired. Maybe it's something else, but the information they give you after donating states the symptoms can last up to a full week. So, I guess I'll see next week if I'm doing better. Also, I can hear whooshing in my ear every time my heart beats.
I've checked some sites and it seems that the symptoms I'm feeling are equal to anemia. I'm not saying it's what I have, just sounds similar. I don't really like to diagnose myself, but like to be informed of things that might be going on with my body.
Luckily my next donation date is the first week of May. But it's not gonna be the double red blood cells, just the normal donation.
