How long does pleurisy last?

Pleurisy usually lasts between a few days and two weeks, according to WebMD. During this time, the treatment may involve antibiotics if the cause is bacterial.

Treatment for pleurisy usually depends on the underlying cause, the Mayo Clinic states. If it is viral, the virus clears up on its own. Most people experience a full recovery, providing the cause is found early enough to begin treatment. To make the condition less painful, some doctors prescribe painkillers, such as nonsteroidal anti-inflammatory drugs. Some patients find they can reduce the pain by pressing a pillow against the painful side or by lying on it.
