While at depth I figure the increased pressure on the blatter will cause the need.
Your bladder should be non-compressable since it is fillled with fluid. For this reason, I believe any solid or fluid part of your body would not feel any effects of pressure...
Only air spaces can feel pressure...

Only a question? This would indicate that there is no reason for DCS or DCI? While I was not speaking of the blatter it self but the areas around. And ones "feel" may be a perseption of some other affect. Your body is not a solid such as a tank but can be made to change shape. An example would be the stress ball that you squeeze. It changes shape but still has the same volume ect...or a cause of death in car accidents may not be the impact but the sudden stoping which is caused by the impact and the trama caused to the organs moving inn the cavities. Just a thought.
