Small amount of mucus dicharge is normal
Kindly don't insert your finger in the anus. It will cause trauma to the lining epithelium.
Mucus production is a normal process of intestinal cells where it tries to protect the epithelium
Causing trauma to the region will further increase mucus production ( as it is a protective response as I told previously )
Next Steps
kindly don't probe the anus with your finger as it will cause trauma
Health Tips
don't worry. unless and until you don't have copious mucus discharge or increased pain and bowel motility ( increased cramps and increased need to go for defecation)
