For me, there are five tell tale signs that my hemoglobin is really low.
- Ringing in the Ears. When my hemoglobin is low, I have a faint and constant ringing in my ears. Most of the time I’m not aware of the ringing; it’s only when there isn’t much noise going on around me that I hear it. Sometimes it is loud enough to hear over the TV.
- Hear My Heartbeat in My Ears. Any kind of physical activity—something as light as putting on my cloths—my cause me to hear my heartbeat in my ears. After a few minutes, the sound will go away; but sometimes it takes some time.
- Increased Heartbeat. Like #2, physical activity as light as getting dressed can cause my heart to race. Sometimes it feels like my heart is going to pound out of my chest; but it’s usually that bad only if I’ve performed some sudden physical exertion.
- Extreme Tiredness. Becoming tired easily is just part of having Sickle Cell Disease. But when my hemoglobin is low, I am super tired all the time.
- Mental Cloudiness. When my blood is low, I’m just not all there. Focusing, concentrating, and holding my attention on anything is difficult. I will also have a hard time collecting and expressing my thoughts.
