Chest X-Rays, Cough, Colds... Oh my!

 If you’ve been feeling under the weather with a cough, nasal congestion, fatigue, chills, or fever in the past few days, you might wonder if you need a chest X-ray. This article provides general information to help you understand when chest imaging may or may not be considered — but it should not replace professional medical evaluation.

General Education

Chest X-rays are a diagnostic tool used to visualize the lungs, heart, and chest wall. They can help detect conditions such as pneumonia, heart enlargement, or fluid in the lungs. However, for many respiratory infections — including Influenza, RSV, COVID-19, and the common cold — an X-ray isn’t always necessary early on, especially if symptoms are mild and your physical exam is normal.

Common Scenarios & Red Flags

In many cases, symptoms from viral respiratory illnesses may peak around Day 3–5 and then gradually improve. A chest X-ray might be considered sooner if you:

• Have shortness of breath or trouble performing daily activities without frequent breaks

• Notice fevers that are becoming more frequent or persistent

• Have a history of asthma, COPD, immune system issues, or prior pneumonia

• Are in an older age group or have other chronic health conditions

When to Seek Care

If your symptoms significantly worsen after several days, or if you develop new breathing difficulties, it may be appropriate for your healthcare provider to order a chest X-ray. Remember: Even a normal chest X-ray does not rule out all types of pneumonia, so follow-up is important if you are not improving. Seek urgent or emergency care immediately if you have severe shortness of breath, chest pain, confusion, or bluish lips/face.

Key Takeaway

Chest X-rays can be a helpful part of diagnosing certain respiratory conditions, but they are not always needed in the first few days of illness. Your healthcare provider will consider your symptoms, medical history, and physical exam to determine if and when imaging is appropriate.
