What type of decompression sickness involves larger joints and dull pain that worsens with ascent?

Type 1 Bends is characterized by symptoms that typically involve the larger joints and present as a dull pain that often intensifies with ascent. This condition arises when nitrogen is released from the body tissues into the bloodstream during decompression, resulting in bubble formation, which predominantly affects the musculoskeletal system. Individuals experiencing Type 1 Bends may notice that their pain in the joints becomes more pronounced as they ascend, due to the decreasing pressure that further allows nitrogen bubbles to expand.

In contrast, Type 2 Chokes mainly affects the respiratory and circulatory systems and can lead to more severe symptoms, including chest pain and neurological impairments. Type 3 Neurological symptoms involve the central nervous system, presenting with a range of neurological signs including altered mental status or motor function issues. Type 4 Skin refers to cutaneous manifestations of decompression sickness, such as rashes or lesions, and does not typically relate to joint pain. Each type of decompression illness has its own distinct features and presentation, making Type 1 Bends the suitable choice for the described symptoms.
