Actually, it's mentioned in the manga (like in the first chapter), that it's like decompression sickness. So you're not totally wrong. In fact, most of the symptoms of the curse are exactly the same as decompression sickness, even the effects on the body after a long time are similiar to decompression sickness on the skin.
