I inserted a finger inside my anus in order to help myself because i felt some soft stool that was stuck inside. later that day, i passed gas and when i looked, i had some mucus on my underwear. could the mucus be due to irritation from fingering?

Constipation.: Yes it is quite possible, but if persists would need to be evaluated further. Would not recommend using a finger except by a physician for dis-impaction as it can cause trauma. Would recommend a good healthy life style to minimize constipation. Increase fibers in diet with fruits and vegetables and whole grains. Increase water intake, decrease caffeine, alcohol. Increase exercise and sleep well.
