I have unexplained anemia as well. Except mine isn't on and off. Last time I went to the Dr. he said my levels are dangerously low. I didn't ask for the specific #'s or anything. He prescribed me iron pills, but they make me sick to the stomach. I wish I knew how I became anemic or why I'm anemic.. but its left unanswered. Last night I had the worst headache of my life that I couldn't sleep, and my neck felt so stiff it was hurting my jaw as well. I was so scared I was having some kind of stroke or something. I'm only 23 years old tho, I don't think that could happen to me. Another scary symptom I have is when I stand up I get so dizzy for about a minute but then it passes. I took Bayer, but that didn't help much :yawn: , so I ended up crying myself to sleep. I really feel like my issues from last night are anemia related. I just wish there was a solution, and I wish I knew where this is really coming from. So, your not alone out there. I'm just as lost as you :confused:
