Anyone who has undergone pneumonia knows how difficult it is to return to daily activities such as physical activity or even housework. The matter may seem trivial, as we have cured ourselves, so strength should automatically return to us. Unfortunately, in the case of pneumonia, it is not so simple. The illness can be caused by viruses or bacteria. While with viral pneumonia the treatment often ends at home, with bacterial pneumonia it happens that the patient may even end up in hospital. It is worth remembering that illness is never indifferent to the body.
