Fatigue

I can't believe how tired I've been for the last 5 days. I seem to have slept loads during the day and still am able to sleep okay at night. It's not right and I'm not sure why I'm so tired but I don't seem to be improving even though I've slept so much recently. I've also been feeling quite ill with it too and I'm feeling weak, I've got bad muscle pains in my back and I can hear my heart pounding in my ears. I've also been suffering with headaches.

I rang my District Nurse today and she's been to take a blood sample because my haemoglobin could be low again.
