Believe it or not one foot is the correct length for a stool. Have you ever had your kidney function tested, and when I say tested I mean by a lab that tests above CKD3(chronic kidney disease) and looks at CKD2 and CKD1.
Almost every one symptoms could be related to kidney dysfunction. Having a full blood count done would not be a bad idea either.
If you ever itch a lot and/or get very dry skin and /or bruise easily then I would def have them tested.
