Is It Decompression Sickness? Symptoms After Swimming - Diving Medicine

More Info

---

Decompression sickness (DCS), commonly known as "the bends," typically occurs when a diver ascends too quickly after spending time at depths where the pressure is significantly greater than at the surface. This condition is primarily associated with scuba diving and is caused by the formation of nitrogen bubbles in the bloodstream and tissues as pressure decreases during ascent. However, your situation seems to involve swimming in a shallow pool, which makes DCS less likely.
Based on your description, it appears that you experienced discomfort after attempting a specific maneuver in the water, which may have caused a sudden change in pressure or strain on your body. The symptoms you mentioned—head heaviness, dizziness, visual disturbances, numbness in the limbs, and nausea—could be attributed to several factors, including:
1. Hyperventilation or Breath-Holding: If you held your breath or hyperventilated while attempting the maneuver, it could lead to dizziness and a feeling of lightheadedness. This is often exacerbated by anxiety or panic, especially in a swimming environment.

2. Physical Strain: The act of bending or twisting your body in the water while being held down could have caused strain on your neck or back, leading to discomfort and symptoms like dizziness or a heavy head.

3. Ear Barotrauma: If you submerged your head underwater while attempting to bend, you may have experienced pressure changes in your ears, leading to discomfort and a feeling of fullness or heaviness in the head.

4. Dehydration or Fatigue: If you are on a diet and possibly not consuming enough fluids or nutrients, this could lead to feelings of dizziness and fatigue, especially after physical exertion.

5. Anxiety or Panic Attack: The sensation of being held down and the subsequent discomfort could trigger anxiety, which can manifest as physical symptoms like dizziness, numbness, and nausea.

Given your symptoms, it is important to seek medical attention to rule out any serious conditions. You should consider visiting a healthcare provider who specializes in internal medicine or neurology. They can conduct a thorough evaluation, including a physical examination and possibly imaging studies, to determine the underlying cause of your symptoms.

In the meantime, here are some recommendations:
- Rest and Hydration: Ensure you are well-hydrated and allow your body to rest. Avoid strenuous activities until you feel better.

- Monitor Symptoms: Keep track of your symptoms. If they worsen or if you experience severe headaches, persistent dizziness, or any neurological symptoms (like weakness or severe numbness), seek immediate medical attention.

- Avoid Swimming Until Clear: It may be wise to refrain from swimming until you have consulted with a healthcare professional and received clearance.

- Discuss with a Professional: If you have ongoing concerns about your symptoms or if they persist, consider discussing them with a healthcare provider who can provide tailored advice based on your specific situation.

In conclusion, while decompression sickness is unlikely given the context of your swimming experience, it is essential to address your symptoms with a medical professional to ensure your safety and well-being.
