Which symptom is commonly associated with septic arthritis?

Increased warmth at the site of infection is a classic symptom associated with septic arthritis. This condition usually occurs when bacteria or other pathogens invade a joint, leading to inflammation. The inflammatory response raises the temperature in the affected area, resulting in noticeable warmth. This symptom, along with other signs like swelling, redness, and pain, helps clinicians differentiate septic arthritis from other types of joint conditions.

Chronic back pain is typically not associated with septic arthritis as it pertains more to chronic musculoskeletal conditions. Night sweats may suggest a systemic infection or other chronic conditions but are not specific to septic arthritis. Loss of appetite can occur in many diseases, including infections, but is not a definitive symptom of septic arthritis. Increased warmth, specifically at the joint site, is a key indicator and plays a critical role in recognizing and diagnosing this condition.
