Sorry to hear that. I have seen more than 20 cases of C. Marmorata in my diving past. It is the easiest one to deal with because it is something you can see and it is probably most common. In each case I have seen there was enough insult in dive profile such as multi-day diving or diving > 45 feet.I'm well aware, very well aware of how they look, feel, evolve and abate.
Could this be because symptoms of DCS and AGE are similar and rarely distinguishable? They both are often classified as DCS and then you do not need the depth and time.Depth and bottom time are just some of the factors in decompression stress. Multiple ascends, or depth changes are another.
There are these famous cases of norwegian fish farmers using scuba to clean the nets underwater, and doing multiple very shallow dives per day (taking 6-9m depth) and getting bend. I can't find the source now but I'm sure someone will post it before I have time to look for it.
Same can be said for example of OW instructors teaching a lot of pool sessions, very shallow but a lot of ascends in a day.
While I know it is not common, I have read of shallow water DCS around 20 feet or above, so it seems while not likely, still possible. Or maybe the reports and such were simply incorrect
We just had a long and very informative thread on this a few months ago. Like this one, it started with a lot of "I heard that..." and "I once read about a study that..." comments. About halfway through it had some real information.Do some looking at Steve Bogaerts, it happens. Since his leaving diving, many have reached out to him with very similar stories.

Here is the thread: Is DCS possible under 20fsw, or 100% impossible?
Here is one of the studies mentioned: Bubble formation and decompression sickness on direct ascent from shallow air saturation diving - PubMed
The gist is that you don't get bent shallower than 20 feet.
