Fissure or hemorrhoids? The pain rule that tells them apart

What is the pain rule for fissure vs hemorrhoids?

When a patient tells me “I have hemorrhoids”, my first question is always the same: does it hurt when the stool passes? The answer sorts most cases before any examination.

• Fissure: sharp, cutting pain during the bowel movement, followed by burning or throbbing that can last minutes to hours. The pain is the main complaint, and blood is a minor detail.
• Internal hemorrhoids: usually no pain at all. They bleed bright red, sometimes enough to drip into the bowl, or they slide out and go back in. Many people feel only a fullness or a lump.
• External hemorrhoids: mild discomfort, itching or difficulty cleaning, unless a clot forms inside. Then they hurt a lot, but the pain is constant, not tied to the stool.

The rule works because the two conditions are physically different. A fissure is a tear in the anoderm, a skin packed with nerve endings, held open by a tight internal sphincter. Hemorrhoids are swollen vascular cushions; the internal ones sit above the dentate line, where the lining has very few pain fibers. That is why internal hemorrhoids bleed without hurting and why a fissure hurts so much while bleeding so little.

What are the differences between a fissure and hemorrhoids?

The side-by-side view below goes further than our fissure vs hemorrhoids overview. Use it with your own symptoms, not as a diagnosis.

How is fissure bleeding different from hemorrhoid bleeding?

Both give bright red blood, because both bleed close to the exit. The difference is in the amount and the circumstances.

• Fissure: a few spots or a streak on the paper or on the stool, usually with a hard stool and always with pain.
• Internal hemorrhoids: can be more generous, dripping or splashing into the bowl after the stool, often painless and sometimes alarming to see.

Neither of them explains blood that is dark, maroon or mixed into the stool. That blood comes from higher up and needs investigation. And because hemorrhoids are so common, they should never be taken as the explanation for new bleeding after age 45 without a colonoscopy when the doctor recommends it.

I can feel a lump: is it a hemorrhoid or part of a fissure?

This is where most confusion happens. A chronic fissure often forms a sentinel pile: a small, soft skin tag at the outer end of the tear, usually at the back of the anal opening. It does not bleed or prolapse, and it does not go back inside. Many patients, and some doctors, call it an external hemorrhoid and treat it with hemorrhoid creams for months.

Clues that a lump belongs to a fissure: it sits exactly in the midline, at the back (or at the front in many women), it appeared after weeks of pain with bowel movements, and the pain is right next to it. Clues that it is a hemorrhoid: it is soft, comes out with straining and goes back in, or it is a firm bluish lump that appeared suddenly and hurts constantly. We explain the skin tag in detail in Sentinel pile: what is the lump next to a chronic anal fissure?.

A lump that is hot, red, swollen and increasingly painful, especially with fever, is neither: it suggests an abscess and needs a doctor without delay. See Fissure, fistula or abscess? How to tell them apart.

Can you have a fissure and hemorrhoids at the same time?

Yes, and it is common. Constipation and straining favor both. In practice we often see a patient whose painless hemorrhoidal bleeding has been known for years and who suddenly develops cutting pain with every stool: a new fissure on top of old hemorrhoids.

When both are present, the pain usually comes from the fissure, so treating the fissure first is what makes the patient feel better. Hemorrhoid procedures such as banding are generally postponed while a fissure is open, because they can increase pain and spasm. A colorectal surgeon decides the order after an examination.

Why does it matter which one you treat?

Because the treatments act on different problems. A fissure stays open because the internal sphincter is in spasm and starves the tear of blood. Hemorrhoid creams contain local anesthetics, vasoconstrictors and sometimes steroids. On a fissure they may soothe for an hour, but they do not relax the sphincter, and steroids thin the skin if used for long. Hydrocortisone should never be used for more than 7 days.

Weeks pass, the fissure becomes chronic (more than 6 to 8 weeks), and treatment gets harder. That is why we explain in Why hemorrhoid creams do not close an anal fissure (and what does) why these creams rarely close a fissure. For a confirmed fissure, colorectal guidelines recommend soft stools and a sphincter-relaxing ointment, nifedipine or diltiazem, two to three times a day for 6 to 8 weeks, with nitroglycerin 0.2–0.4 % as an alternative that causes headache in up to half of patients. If that fails, botulinum toxin or lateral internal sphincterotomy come next. Our guide on Which anal fissure cream actually works? A surgeon’s guide by fissure type covers the options.

When should you see a doctor instead of guessing?

Telling a fissure from hemorrhoids at home is reasonable for mild, typical symptoms. Some situations should not be self-managed. See a doctor without delay if you have:

A colorectal surgeon can usually separate a fissure from hemorrhoids in a short, gentle examination. If you want to review your symptoms first, try our 2-minute symptom self-check, or contact our team.

Where does FISURIN fit?

FISURIN is a fissure cream, not a hemorrhoid cream. Our surgeons at Clínica Proctológica de Lima prescribe it for confirmed fissures, especially chronic and post-operative ones: nifedipine to relax the internal sphincter and lidocaine to ease the pain of each bowel movement, in a water-based hydrogel with a written 6-week protocol. It does nothing for prolapsing or bleeding hemorrhoids, does not replace soft stools and does not work in a few days. Today it is a magistral formula prepared under prescription in Peru and is not shipped abroad; FISURIN Hydrogel and FISURIN Relief are in preparation, with a waiting list.
