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.
Feeling sleepy and tired all the time can be a sign of fatigue. Tiredness and fatigue can manifest in a number of ways. According to eMedicineHealth, fatigue can cause weakness, dizziness, tiredness, shortness of breath and even palpitations.
The feeling of always being tired is very subtle and not quickly identified by a person just developing heart disease. In fact, if no other obvious symptoms are exhibited, the affected person will dismiss this heart disease symptom by thinking, I am working too hard. I need some time off.. This is just bad thinking. If you are tired all the time it is because you have become de-conditioned and your heart cannot stand the strain.
