you could try " i don't know... lots of people's bodies do things that they don't understand... that's why med researchers will always have jobs. However this happens often enough that I know it's not an emergency" Sometimes when people ask "why" they really mean " you won't d*e will you?!" and they just need to hear " I am fairly sure that the answer is 'not yet' but thanks for asking"

my feet swell 3 sizes bigger shoe wise occasionally and people ask "why" and i don't know but most of the time why really means " will you kick it or will your feet fall off?" once they hear I have been checked and rechecked and it evidently just happens, but it doesn't mean anything emergent they stop asking
