​Could you send me information about hyperbaric chambers in the area where I'll be diving next weekend?

​I understand that arterial gas embolism (AGE) can manifest like a stroke, with facial droop and cognitive problems. It makes sense that bubbles in the brain could cause such serious symptoms, but I have also heard about facial droop occurring with much less severe dive injuries. How could this happen?

In a recent DAN article about exercise and diving, I read the following:

Intense physical activity — generally with substantial muscular forces and joint loading (the application of forces on joints) — is believed to transiently increase micronuclei activity, the presumed agent of bubble formation.

Are these micronuclei preexisting? Where do micronuclei come from, and how are they formed or created?

​I recently returned home from a two-week liveaboard dive trip. After experiencing some initial motion sickness while adapting to the motion of the boat, I had a wonderful trip. At the end of the trip, however, I felt like the dock was rocking when we disembarked. I was queasy and almost vomited. This feeling continued for nearly a week before resolving. Why did this happen?
