What Happens If Knee Bursitis Is Not Treated?

A bursa is a small fluid-filled cushion that reduces friction near the knee. Repeated kneeling, pressure, a knock, or another inflammatory problem can make it swell. Continued pressure may keep the area enlarged and sore, causing knee pain and making kneeling or bending difficult. Infection is less common but matters because the skin may become warm or red and you may feel unwell. Bursitis is different from arthritis inside the knee, so diagnosis helps guide care.

Reduce kneeling and direct pressure while symptoms settle, and use only medicines suitable for your health history. A clinician can examine the swelling and decide whether fluid testing or joint aspiration is appropriate. Anti-inflammatory medication may be suggested when safe. Persistent or recurrent bursitis may need evaluation for the provoking activity or, rarely, bursa removal.

Seek same-day medical advice for a red, hot, rapidly enlarging swelling, fever, drainage, or feeling faint or unwell. Seek urgent care if you cannot move the knee or bear weight. Make a routine appointment when swelling or knee pain continues despite avoiding pressure.

Is the swelling in a bursa or inside the joint? Could it be infected? Should fluid be aspirated or tested? Which kneeling changes and medicines are safe for me?
