What is Pneumonia?
Pneumonia is an infection that inflames the air sacs in one or both lungs. The air sacs may fill with fluid or pus (purulent material), causing cough with phlegm or pus, fever, chills, and difficulty breathing. A variety of organisms, including bacteria, viruses, and fungi, can cause pneumonia.
What Does Pneumonia Feel Like? Symptoms to Watch For
The way pneumonia feels can vary greatly depending on the cause, your age, and your overall health. However, several common symptoms are characteristic of this lung infection. Understanding these symptoms can help you recognize when to seek medical attention.
Respiratory Symptoms
The most noticeable symptoms of pneumonia often involve the respiratory system. You might experience:
- Cough: This is a hallmark symptom. The cough can be dry and hacking, or it can produce phlegm (sputum). The phlegm might be greenish, yellowish, or even rust-colored, and sometimes it can contain blood. The cough can be persistent and difficult to suppress.
- Shortness of Breath (Dyspnea): You may feel like you can't catch your breath, especially when you exert yourself. In severe cases, shortness of breath can occur even at rest. Breathing may also become rapid and shallow.
- Chest Pain: This is often described as a sharp, stabbing, or dull ache in the chest. The pain typically worsens when you breathe deeply or cough. It can sometimes radiate to your shoulder or back.
Systemic Symptoms
Beyond the lungs, pneumonia can affect your entire body, leading to more general symptoms:
- Fever: A high fever is common, often above 102°F (38.9°C). It can be accompanied by sweating and chills.
- Chills: You might experience shaking chills, which can feel quite intense.
- Fatigue and Weakness: A profound sense of tiredness and lack of energy is very common. You may feel too weak to perform daily activities.
- Muscle Aches (Myalgia): Similar to the flu, you might experience generalized muscle soreness.
- Headache: A persistent headache can also accompany pneumonia.
Other Potential Symptoms
Depending on the type of pneumonia and the individual, other symptoms might include:
- Nausea and vomiting
- Diarrhea
- Confusion or changes in mental awareness, especially in older adults
- Lower than normal body temperature (hypothermia), which can occur in older adults or people with weakened immune systems.
When to See a Doctor
It's crucial to seek medical attention if you suspect you have pneumonia. While some cases might resolve on their own, prompt diagnosis and treatment are essential to prevent complications. You should see a doctor if you experience:
- Difficulty breathing
- Chest pain
- A persistent fever (especially if it's high)
- A cough that produces discolored phlegm or blood
- Symptoms that worsen or don't improve after a few days
- Confusion or disorientation
A doctor can diagnose pneumonia through a physical examination, listening to your lungs, and possibly chest X-rays, blood tests, or sputum tests. Treatment usually involves antibiotics for bacterial pneumonia, antiviral medications for viral pneumonia, or antifungal medications for fungal pneumonia. Rest, fluids, and fever reducers are also important parts of recovery.
