Hi all. First a brief history:
As a kid I work at Magic Mountain…a park full of rollercoasters. Never had a problem riding all day long. I also grew up around and on boats, sailboats mainly. Never had a problem above deck, but did have issues going below while under way.

OK, fast forward to 12 years ago. Crashed a motorcycle bad..real bad. Bad enough to break bones and crack my helmet. After a long recovery, I found that rollercoasters were now out. The first time I tried was just a very small one at a fair and I was sick for 3 days.
At that time I talked to my Dr., who (if my now failing memory serves) mentioned it was likely small bubbles on my middle ear.

On to the diving part…. I have owned several small boats since my accident. Never a problem with sea sickness., but on dive boats…..you get the point. I get sick (lightheadedness, dizziness, nausea but not to the point of vomiting). Interestingly, it all goes away once I am under the water. There have been 2 underwater issues as well. One a few days ago and one several months ago. The more recent was off a dive boat, my first dive after feeling ill. The other was a shore dive, feeling fine. The effects were the same however. After descending to about 30 feet I got slightly confused, a little dizzy and disoriented. I had to stop and regain my wits. I remember trying to look at my depth gauge to see if I was deep enough to be narked (never been nark, so I don’t know if it is the same feeling). I stopped, concentrated on breathing and both times it passed in 5 to 10 seconds. Both times I had no further issues during the dive.

These may or may not be related issues, but I thought I would post and get some thoughts from the dive community. YES YES YES, I do plan on seeing my doctor about it all.

Thank you in advance.
 
The following opinions are of an amateur diver who is not a medical pro, but I'll offer a couple of suggestions...

Not narked, but motion illness and vertigo.

Sounds like the injuries maybe left you with some ear problems, and you may want to see an ENT for a check-up in that area. And a crash that would crack a helment (and we still see idiot on cycles without them!) could certainly affect the ear area, perhaps leaving your more prone to motion sickness than before. Based on those maybes...

No, the person driving the boat hardly ever gets hit even if everyone else may be affected. There are a great many threads on motion/sea sickness - easy to :search:

You might find using some decongestants and/or antihistamines the night before and morning before diving - again, check with your medical pro and try taking them when you don't expect to dive, drive, or operate machinery in case of a reaction, and you may well benefit from additional training and work in ear equalizing, even the day before and morning before.

Hi robertarak,

DandyDon has raised some good food for thought.

In the meantime, what you are experiencing is almost certainly not related to nitrogen narcosis.
