Drake,
I hope if they find something, that it is minor and can be fixed or treated so you get some relief.
I haven't flown since 9/11 but once for an attempt to get to my younger brother's funeral. The plane broke in Dallas so never got to upstate New York. Just turned around and flew the commuter turbo prop back to Shreveport Regional. I flew a lot until I retired from the military in 1998. Colombia, and Germany were long hauls to me. The Philippines is a really long haul.
