Sinus issues that may be small enough not to be noticeable normally can become very noticeable with the pressure difference. Aftermath (or the start of) a cold that you don't notice can be enough. Nausea can be affected by anything that impacts the inner ear, so sinus pressure etc. can have an effect.
I wonder if I have some pressure sensitivity that affects me on these long haul flights, as I haven’t felt it on domestic flights or flights from SFO to Heathrow (or back). In addition, I know I am susceptible to altitude sickness.
