I've never had a rash, joint pain or any other symptom. I lost my commercial logbook in the great flood of 2017. In that logbook, everything is tracked. Pain, rash, stupid tenders who forgot to fill the air supply compressor with fuel, even a dive to 271' on air when we lost our helium supply mid dive. Anything and everything is very specifically accounted for on a commercial logbook. Especially in the GOM. It took me 12 minutes to hook up a shackle from the crane. That was noted.
We got paid for being under pressure, DCS treatment on an oil rig paid $1/foot. I promise if I was bent, I'd get paid for it.
