Swelling in the feet is not related in any way, that I am aware of, to gall bladder problems. It's just like Josey said, bad gall bladders can be herditary, but it is weird that your daughter has the same symptoms as you right this minute. I think both of you should see a doctor together and say hey, look, we're both having these weird symptoms. Can you test us for things that would cause these symptoms and could be caught by two people in the same house? Parasites and c. difficile can both be transmitted by toliet seats, although I think diarrhea is the usual symptom for all of them (clean toliets with bleach to kill all these bugs). You may both be allergic to the same thing since allergies are also often herditary; have you changed your cleaning products lately? Have you any cause to have gotten mold in your house? Have you gotten a new pet? I can't really figure out how an allergic reaction to something other than food would cause constipation, but then swelling of the extremities is not really a symptom of gut problems either; you may have two seperate things going on at once.
Make sure you analyze what you are eating as well. I know once, when I was growing up, that I complained to my mother of suddenly being constipated and she said that she was bad constipated too and we finally decided that the dehydrated banana chips we were eating was making us constipated. So be sure to look at foods that both you and your daughter are eating as a possible culprit. Or, if you are both on a diet; low fat diets can lead to constipation, as can the low-carb ones.
