  1. Sneezing
  2. Pain, especially near the joints ✔
  3. A sore throat

Why: Nitrogen bubbles can collect near joints and muscles, causing an ache that can grow. Numbness and tingling come next on DAN's list. Any of these after a dive means see a doctor.

Huh, didn't know that: Unlike a sprain, DCS pain usually does not get worse when you move the joint.

The dad joke
If your elbow aches after a dive, don't play it cool. Tell someone, even a clam would speak up.
