F/A-18 pilots are reporting the same issue.
They recently flew three pilots off a carrier so they could undergo treatment in a decompression chamber.

I stand corrected on the F/A-18 Super Hornets. I guess the super Hornets use a similar OBOGS as the F-22. Memory tells me the A/C variants still use LOX.

Seems to me a hypobaric chamber would be used for decompression issues and not hypoxia. Hypoxia is usually self remediating if O2 is returned.

I dreaded the annual altitude chamber certification because of the mighty headache to follow.
