One reason that it takes so long for people to recover from pneumonia is because of all of the byproducts and debris that is left behind in the lung tissue. While antibiotics help kill the bacteria, your body’s internal weaponry must then work to clear your lungs. This often leads to prolonged and severe coughing and shortness of breath with any significant exertion.
In addition to the energy used in the process of chronic coughing, lingering symptoms of fatigue and weakness can also be pronounced. There's no surefire way to predict how long it takes for anybody to recover from pneumonia, but those individuals who are not an optimal health at the onset of illness will take longer to recover.
During recovery, it's important to stay in contact with your primary care physician, who can help you deal with any other potential complications. A local qualified and certified urgent care like Lakes Urgent Care, is another resource if your primary care physician is not available.
