A must read regarding some case studies on deompression sickness can be found at:
- "The Last Dive"...a must read!!!!! it goes off on tangents, but they are interesting tangents and well taken case studies of accidents such as DCS.

http://outside.away.com/outside/features/200508/dave-shaw-1.html ....a much wiser scubaboardian posted this link....I am just re-copying it. This link has an excerpt of DCS, as well as a gutwrenching fingerbiting read through of a tearful dive accident.
As far as pain goes, I think I could handle the pain of DCS....including, in extreme cases, loss of hearing, loss of sight, and paralysis....if AND ONLY IF the sight, hearing, and paralysis were only temporary. However, the case is that some percentage, if not all, hearing damage, sight damage, and paralysis is sometimes permanent. Ugh. Not good.
I guess I am to the point of "who cares how painful it is, let's just work dilegently to avoid situations and actions leading up to it happening to you/me/us."
Just imagine a half hour to an hour and a half wait for USCG...or in foreign countries, possibly a 2 hr wait for a medivac chopper to take you to a recompression chamber. Imagine that there is only room for you on the medivac and not for anyone from the boat who can make sure that your urgent need for a recompression chamber is communicated to all involved in your treatment, and imagine that once at the recompression chamber hospital, possibly hundreds of miles away, you are left alone with a chart at the foot of your gurney. Now imagine passing out, and someone making the mistake of treating you as non emergency, leaving you in the que for several more hours before realizing you needed to be placed in a recompression chamber. Another nightmare would be in a foreign country, not speaking the language, and a hospital staff not given proper breifing on what is needed for your treatment. This is probably a worst case doom and gloom scenario, not actually possible. I just assume leave nothing to chance.
There are several descriptions of how the Nitrogen damages your tissues and nerves, including cut off of oxygen to the muscles and organs. However, I always get this incorrect, god aweful image of nitrogen bubbles expanding between layers of tissues, stripping / shredding the muscular and organ tissue like one would strip pork for making tamales. I know this is incorrect, but that image tends to keep me in check.
