Hi all,

Well I have a cautionary tale called How To Get Bent, otherwise known as The Stupidest Day of Diving Ever. This is a long post and if anyone reads it, I would be glad to hear anyone's opinions.

I haven't dived in ten years, but my husband and I were going to the Caribbean so we decided he would get certified and we would do some diving. We flew from our home in Oregon to Saba. I can't sleep on flights so I was pretty trashed by the time we got to Saba (had slept only a few hours during our redeye flight overnight) and then when we got to Saba I began to worry and become nervous for the next day of diving. I then couldn't sleep again, so in the two nights preceding my first dives in ten years I got maybe 2 hours of sleep each night. I was no doubt dehydrated, too.

The next day I get on the boat and we do a multilevel dive down to about 80 feet at max depth, gradually ascending throughout the dive to maybe 40 feet before surfacing. We were diving based on our dive master's computer and he said it would be "to NDL." I was sucking air out of nervousness and surfaced a good 15 minutes at least before everyone else did (they stayed down about an hour). The mooring line was at 40 feet and as I recall I surfaced along the line at probably a good pace, but who knows, maybe I went too fast? That's not even the best part.

I didn't do a safety stop. Why? I just forgot. How can I defend this? I can't. It was just stupidity.

I was scheduled to do three dives that day but after I got up, I felt OK except seasick. I decided to sit out the next dive and went to the hotel, where I immediately laid down on the hotel room bed and slept for an hour straight. Total surface interval was about 2.5, maybe 3 hours. Went back to the boat feeling great. Did the second dive, the same site, multilevel down to about max 70 or 75 feet this time and I was down a bit longer, maybe 50 minutes instead of 45? Again surfaced before everyone else for the same reason (fast air consumption). Again, dubious ascension and no safety stop. Again, indefensible. Afterward I felt great. We went back to the hotel and everything was fine.

The next day I felt great, went back and did three dives, and felt much better about everything. This time I did the safety stops as required and ascended appropriately. I thought, "Wow, wtf was I thinking not doing the safety stops yesterday?" I went back to the hotel and thought about the risks I had taken the day before and googled "DCS symptoms." I had a pain in my ankle, typical to pains I've had before. It felt like a mild tweak due to the fins or possibly the massive amounts of climbing up and down Saba's copious hills and steps. I'm serious, this is the steepest place I've ever vacationed. The cars back to the hotel had trouble nagivating the hills at least twice, and our room was up so many steep flights of steps that I had to take a break to breathe about halfway up! So I hadn't thought twice about the mild ache in my ankle.

Reading about DCS symptoms, my hypochondria, which has been a problem all my life, began to loom. I began to feel my ankle pain magnify to enormous acuity (given that it's now gone away, and it only occurred while walking or flexing the ankle, and was minor, this seems to have not been a symptom of DCS). Then I thought, "Wow, my feet are tingling...I think....Are they tingling?" (it was really minor.) "But they always tingle like this. Is this the bends?" I concentrated on them. The tingling seemed to become more obvious. I only noticed it when I thought about it, but I began to think about it all the time. It was bilateral. I asked the hotel owner, himself a dive instructor, what he thought. He said, "I'm no doctor so I can't say. But I think you're fine." I asked the dive shop what they thought. They said, "That was really not smart of you. That's how people get hurt. If we had known it had been ten years, we would've had you in the pool doing a refresher. That said, stop worrying....it sounds like you're fine."

Over the course of a few days the feet tingling went away. A week after the two days of diving, last night, I flew from the Caribbean to Portland. On the flight I began to worry about the DCS again. I thought my hands felt a little clumsy. I touched my fingers to my nose (it worked). I woke up today still feeling like my hands were clumsy. I called DAN. They said, "We can't diagnose you over the phone....get checked out by a doctor. But honestly, the possibility that this is DCS is very low."

What do you think? Should I stop worrying about DCS and start worrying about how to avoid making these mistakes in the future? Although honestly that's not much of a question. What I did wrong is glaring and pretty damn obvious.

Either way, stupid got cured.

Should also clarify that the seasickness went away minutes after getting off the boat. I took Dramamine subsequently and it never recurred.

Should also note that DAN felt that my symptoms were unlikely DCS because a) I didn't notice symptoms until about a day or more after the dives, b) the symptoms are consistent with psychosomatic ones, c) the hand clumsiness was not accompanied by numbness or tingling and occurred after a flight, yes, but about a WEEK after the dives, and c) bilateral is not what they usually expect to see.
 
Thanks for sharing your story!

Good that you didn't get seriously hurt, and while I'm certainly no hyperbaric doc, I would agree with the DAN representative who said that the likelihood of this being DCS was pretty low... If you focus on a symptom enough, it certainly does seem to self magnify! Glad that you are aware of your issues, which should improve as you dive more, and become more comfortable.

Here are a couple of thoughts about "undeserved" hits.

1) Safety stops are extra buffers. Missing a safety stop on a dive when you were not over NDL is probably less of a risk than a fast ascent. SLOW down your ascents. Fast ascents, especially multiple fast ascents, pump up the bubbles and can make you at risk even if you are within NDL.

2) You don't do any dive, certainly not one "to NDL", using someone else's computer. You should dive tables - unlikely in 2013 - or you have your own computer (rent one or buy one, they are pretty cheap in the context of a week in Saba!).

3) Being hydrated really helps cushion the bubble formation, probably more than a safety stop does. Don't forget to drink.

4) Being a new diver and an "air hog: probably put you less at risk, since your dive was shorter and you took on less nitrogen.

5) Here is the story of how I got bent this fall, I think that you might find it interesting

Dive safe! :)

Thank you Doc! So you think that I'll avoid paralysis this time? :blinking: I don't need to worry about some kind of slow progression of it?

If so, it's more than I deserve. You are certainly correct that I'm aware of the many things wrong. Actually, this seems like a perfect way to get bent, doesn't it? Dehydrated. Over-tired. Fast ascent. No safety stop. Not using my own computer. Multiple dives in a day. No refresher after ten years away from the sport. Also, I didn't mention this before because I'm a vain lady, but I am 5'5" 155. This means I could drop some pounds.

Hahah... well, I don't give advice online about fields that are out of my area of expertise (ask me about earwax, though). :)

But it sounds like you are OK at this point.

Don't know if you read my tale of idiocy, but the take home from both of our stories is that it's often not the one big really stupid error, but the accumulation of lots of low level risks that load the dice to the point that you eventually come up snake eyes...

Now that you are back into it, just keep diving and keep learning!

Happy New Year...

Mike

I did read it, and thank you for your kindness in suggesting that our levels of stupidity are remotely comparable. :wink: I read with interest your notes about the coffee. I have previously read the research your are talking about regarding the relatively new idea that coffee may actually not contribute to dehydration. I noted it with enthusiasm because I love coffee (caffeinated or not) and have always avoided it while flying due to the dehydration, but in the last year or so after realizing that it did not dehydrate you have enjoyed it in transit again.

Yup, that's somewhat controversial and above my pay grade, but I think that if you keep drinking other fluids your body does sort things out. I remember the saying from residency: "The dumbest kidney is smarter than the smartest intern!"

I'll add one more to your list. Exertion after diving. (e.g climbing long flights of steps) People don't think about that one much,but the only time I had a buddy that got bent, post dive exertion was one of the causative factors.

Glad your O.K.

i completely sympathize with you! Being 50 something, I have so many little aches and pains I don't know how I will ever know if I'm Bent. And as a fellow hypochondriac, the problem is greatly magnified!

Thanks....I am too....at least, I hope I am?? I would know by now, right?

Regarding the stairs, I had thought of that. But it was unavoidable, unfortunately.

It sucks the fun out of things, doesn't it? I'm a psychotherapist so you'd think I would be able to self-talk myself out of these panics but so far, it's a case of the cobbler's children going barefoot.
 
I think you have identified most of the issues yourself. I agree that this is a recipe for a problem, whether DCS or something even worse. Long surface interval, no refresher, no computer, poor ascent control and execution . . . This is why so many of us fret over people who are vacation divers. It sounds as though you are okay and just overly worried, but this is really a cautionary tale for others considering similar trips.
