Joint pain is a hallmark symptom of decompression sickness, often referred to as "the bends." This condition occurs when a diver ascends too quickly after spending time at depths, causing nitrogen that was absorbed into the body under pressure to form bubbles as the pressure decreases. These bubbles can cause a variety of symptoms by affecting different body systems, but one of the most characteristic presentations is pain in the joints.

The joint pain associated with decompression sickness is typically severe and may be described as a deep, throbbing ache. It often affects the larger joints, such as the knees and elbows, and is commonly reported by divers experiencing this condition. Understanding the symptomatic response of the body to rapid pressure changes is essential for recognizing and responding to decompression sickness effectively.

Other symptoms such as headache, skin rash, or nausea can occur with various other medical conditions, and while they may also be associated with decompression sickness, they are not as distinctive as the joint pain that is frequently reported.
