Zinc oxide ointment or petroleum jelly applied to the anal opening may help to prevent the burning sensation. Bulk stool softeners will help to avoid the pain occurring with bowel movements. Lidocaine ointment may be recommended. Activity No restrictions.
Physical activity reduces the likelihood of constipation.
