Many patients complain that they are fine when at rest, but when they move a little too hard, they develop a slight fever or become exhausted and unable to move. In such cases, we first check for two causes: first, whether the oxygen level of the blood does not drop when the patient walks. If there was severe pneumonia at the beginning of the infection, the lungs may remain scarred afterward. The effect of this is that the lungs do not expand properly when breathing, making it more difficult to move.
The second is to check for autonomic nervous system abnormalities. We focus on POTS, which develops after coronary infection. There are no symptoms when the patient is sleeping, but palpitations are strong when standing up or moving, and the patient is often aware of the pain.
In some cases, the above causes may not be obvious. In such cases, we provide ongoing medical care, including checking for muscle weakness or strong psychological stress involved.
