What are common symptoms of Type 1 decompression sickness?

Type 1 decompression sickness, also known as "the bends," primarily presents with symptoms that are associated with inert gas bubbles forming in the body due to a rapid decrease in pressure. The most common symptoms include pain, marbling, and swelling.

Pain often occurs in the joints and muscles, typically resembling a deep ache, and is a key indicator of Type 1 decompression sickness. The marbling effect refers to the skin changes that can result from gas bubbles forming in the dermis, leading to a mottled appearance. Swelling is also a significant symptom because the presence of these bubbles can cause localized inflammation and edema in affected tissues.

While fatigue, dizziness, rash, fever, nausea, and vomiting can be related to various physiological or pathological conditions, they are more commonly associated with other forms of diving-related illnesses or unrelated health issues, making them less characteristic of Type 1 decompression sickness specifically. Understanding the hallmark symptoms of decompression sickness is essential for proper identification and treatment in diving scenarios.
