I just received my certification (yeah!) so I've been reading a lot about diving.
When I came across the fact that DCS can occur regardless of prevention, it bugged me out a little. To top it all off, the symptoms seem to be a bit ambiguous (lacking any clear-cut delineation).
How would I be able to tell a muscle ache from a nitrogen bubble flare-up?
If DCS can occur regardless, how do you dive without any day-after DCS "paranoia"?
I've been told that DCS will feel different. I have days when I ache (I'm getting old). I've been told that if you get an ache that is 'different' then see a doctor and tell them you've been diving. Lugging 100 lbs of gear around, wading into surf, etc. will make you use muscles you normally don't. Body aches the next day would be normal (if your old or a little out of shape). But if you get an ache in your elbow that moves to your bicep or it comes and goes away, that might be DCS.
I think I've read articles on DAN about this. Try go to
DAN and reading some of the articles there.
Also, do you worry about alcohol poisoning? If you are drinking 26 oz in 2 hours, yes. If you are drinking 4 oz in 2 hours NO WAY. What about 17 oz in 2 hours? Then it gets a little iffy.
Are you diving 7 times a day below 60' each time? They worry about DCS. Are you diving 3 times a day with only one deep dive (deep is below 60'), then don't worry about it. Are you diving 5 times a day but half the dives are around 50' or less? Then it is a little iffy.
So far, all the guys I've talked to who have been bent are diving a LOT more than I am right now. If I had a job at a resort and was diving 5 times a day I'd worry about it and make sure I'm not drinking diuretics/alcohol, I'm well hydrated, I get the suggested surface intervals, I don't do it 52 weeks a year, etc.
Also, get your Advanced Open Water. Part of it will be deep diving. Any good course will cover the risk factors and you can work at reducing as many as you can. If you are overweight, dive more and lose weight

. Make sure you are well hydrated. Don't go on a drinking binge the night before you plan on diving.
