Does anyone else experience bad intestinal pain after long flights?

[Flaxbee]

the last few times I've flown to Russia thru Germany (from Atlanta, so about a 9-10 hour flight to Frankfurt, then a few more hours into St. Petersburg) I end up with debilitating intestinal pain for about an hour after we've landed. My eardrums are fine, but it's like the pressure in my guts hasn't regulated. It is horrible. Doesn't happen on shorter flights in the US, or shorter flights in Europe -- just seems that anything beyond 6 hours (or maybe it's the elevation, since longer flights are usually flying at higher altitudes) is torture.

Anyone else have this problem? I'm fine after an hour, but in the meantime it's awful, and NOTHING helps. So I know it's just my body regulating itself but am I the only one?
