Thank you for the query.
Strong pain while passing the stool is very characteristic for anal fissure
. Hemorrhoids usually does not give strong pain. Bleeding can be present with both, hemorrhoids and anal fissure and you probably have both conditions.
To help with hemorrhoids you should: keep your stool soft and do not push hard on it, have sitz baths with Quercus Cortex
twice a day, wash you anus after every stool and keep it dry and clean.
Hope this will help.
