By Mayo Clinic Staff. An X-ray is a quick, painless test that produces images of the structures inside your body â particularly your bones. X-ray beams pass through your body, and they are absorbed in different amounts depending on the density of the material they pass through.
Physical Causes. The most obvious reason for being tired and sleepy is lack of sleep. According to MayoClinic.com, the average adult needs between seven and eight hours of sleep every day. If you're sleeping less than that, adjusting your sleeping schedule might provide some relief.
Fatigue: even when I'm well rested, I am super tired all the time! Even after 8-10 hours of sleep, a couple hours after waking up, I am ready to go back to bed. Dizziness: I don't know what causes it, but I get dizzy for long periods of time sometimes. Sometimes I feel like I could pass out, but I never have. Headaches/migraines: when I get dizzy, sometimes I get a headache or a migraine. Last week I got a migraine that didn't go away until yesterdayâ¦. I had it for 6 freaking days. Also, when I'm dizzy, sometimes my heart kind of flutters and my ears ring.
