Right elbow pain after a 300'er on a conservative profile. Had dove that profile before win no I'll results. Breathed o2 on the 5 hr ride home and symptoms went away.

Sure wish you had something there for the subclinical DCS symptoms of extreme fatigue, tiredness, sleepiness . . .
I don't really know how to answer. The first time I went to Nanaimo was the first time I dove a deep (100 fsw) square profile. That night, I had several odd-looking pink-purple stripes on the back of my left shoulder. They looked a little like bruises, but they were gone in the morning. They did not itch, and I don't know whether I had a very minor skin bend or not. (I did a good minimum deco ascent with no control issues, and did not exceed planned bottom time.) I have since done extra deco time when I do deep, square profiles, and have never had anything like this. I should mention that I stood for quite a while with doubles on before the dives.
Do massive air embolisms count in your definition of DCS?
It is unfortunate that there does not seem to be entirely uniform usage on the terminology. But most commonly:
DCS (decompression sickness) is due to bubbles formed from dissolved inert gas in tissues and veins.
CAGE (cerebral arterial gas embolism) is due bubble introduced into arterial circulation due to pulmonary barotrauma.
DCI (decompression illness) is inclusive of DCS and CAGE.
Embolisms fall under CAGE and DCI, but not DCS.
Lippmann, and Mitchell's "Deeper Into Diving", and the NOAA Dive Manual have good discussions of this, as does the DAN website.
