I'm guessing that you fasted except for the apples and did not use Epsom Salts . I would guess that since much of the oo/lj didn't passout of the stomach that the upper intestine was either clogged with apple pulp or constricted due to an irritant, allergy or food intolerance. Or maybe there is a lot of gas formed because of the microorganisms feasting of the apples you ate for the 3 days. If you felt a hard blockage it may have been gas and if so you can use gentle massage to move it along.
Apples can have pesticides, preservatives (commercial not organic) and mold/yeast toxins so all the bruised areas need to be removed, (peeled is best) and vitamin C added to lessen the mold toxins.
I use prune juice or softened prunes, a herbal laxative which helps clear out the upper intestine (Cascara sagrada), grapefruit.
