​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?
