Piles, fissure or fistula? 6 ways to tell what is actually troubling you
Reviewed by Dr. K. Sravan KumarColoproctologist & Laparoscopic SurgeonIn short
Piles, anal fissure and fistula are three different conditions that are often confused. Piles commonly cause bleeding and a swelling that may come out during motion. A fissure causes sharp pain during and after passing stool. A fistula can cause a recurring boil near the anus that discharges pus. Treatment depends on examination, grade and diagnosis; medical, laser-assisted and surgical options are available at Sreshta.
Almost everyone who walks into our OPD with an anorectal complaint uses the word piles. It is the only word most people know for that part of the body, so bleeding is piles, pain is piles, a boil is piles. About half the time the actual diagnosis is something else.
The difference matters because the treatments are not interchangeable. Here are the six signs we use in the clinic to tell the three conditions apart, written the way we explain them across the table.
- 01
1.Painless bleeding points to piles
Fresh red blood on the stool or in the pan, with little or no pain, is the classic sign of internal piles. The bleeding tends to come and go, often after constipation or a spell of straining. If bleeding is your only symptom, piles is the most likely answer, though it still needs an examination to rule out other causes.

2.Sharp pain during motion points to a fissure
A fissure is a small tear, and it announces itself. Patients describe a cutting or burning pain while passing stool that can last for an hour or more afterwards. Many start avoiding the toilet out of fear, which hardens the stool and makes the tear worse. Bleeding, if present, is usually a thin streak on the surface.

3.A recurring boil that leaks points to a fistula
A fistula is a small tunnel between the inside of the anal canal and the skin. The outside opening looks like a boil that heals, fills again and bursts, sometimes for years. Discharge of pus or fluid that stains the undergarments is the giveaway. A fistula does not settle with ointments, however long you use them.

4.A swelling you can push back is usually a pile
Piles that have grown often come out during motion and go back in on their own or with a gentle push. A painful swelling that appears suddenly and cannot be pushed back may be a thrombosed pile, which needs to be seen promptly. A fissure can also produce a small skin tag that people mistake for a pile.

5.Itching and discharge behave differently in each
Piles can cause itching from mucus leakage. A fistula causes wetness from its opening even between flare ups. A fissure is usually dry but tender to touch at one spot. Where the moisture comes from, and when, tells us a lot before we have examined anything.

6.Only an examination settles it
These patterns overlap, and bleeding in particular has causes that have nothing to do with piles, including polyps and, rarely, cancer. A few minutes of examination by a coloproctologist gives a firm diagnosis. Waiting months with the wrong self diagnosis is how a small problem becomes a large one.

No. They are separate conditions with separate causes, though one person can have more than one at the same time. Long standing constipation and straining raise the risk of all three, which is why they often appear together.
No, and this is the important one. Piles are the most common cause of fresh rectal bleeding, but polyps, inflammation and occasionally cancer also bleed. Bleeding that is dark, mixed into the stool, or accompanied by weight loss or a change in bowel habit needs prompt evaluation whatever your age.
