Knee pain is a common issue that can result from injuries, overuse, arthritis, or other conditions. While mild discomfort can often be managed at home, certain symptoms may indicate a more serious issue requiring prompt medical attention.

Call your doctor if you can’t bear weight on your knee or it feels unstable. Seek help for significant swelling, inability to fully bend or straighten the knee, or visible deformity. A fever with redness, pain, and swelling may signal infection. Severe knee pain after an injury also needs urgent evaluation. These signs may indicate serious damage requiring prompt medical care to prevent complications and aid recovery.
