This is a crucial anatomic distinction due to the type of cells that line the hemorrhoid, and the nerves that provide sensation.
Inside hemorrhoids treatment are located above the pectinate line and are lined with cells which can be the same as those that line the remainder of the intestines. Exterior hemorrhoids arise below the line and are covered with cells that resemble skin.

Passing a hard stool can scrape off the thinned lining of the hemorrhoid causing painless bleeding.
However, the swollen hemorrhoid also can trigger spasm of the muscle tissue that surround the rectum and anus causing pain, especially in the event that they protrude or prolapse by means of the anus. A lump may be felt on the anal verge. Inner hemorrhoids also can thrombose (clot) resulting in severe pain.
