17 Sep Anal Fissures vs. Hemorrhoids: How to Tell the Difference andWhy Treatment Isn’t the Same
By Bummed Editorial Team
Rectal pain and bleeding are common enough that most people will experience some version of it in their lifetime, and most people’s first assumption is the same: it must be a hemorrhoid. Hemorrhoids are common — up to 75% of Americans will experience bothersome hemorrhoids at some point, according to the NIDDK (National Institute of Diabetes and Digestive and Kidney Diseases). But a second, frequently overlooked condition, the anal fissure, causes similar symptoms through a completely different mechanism, and the two are treated differently. Getting the diagnosis right matters, because the wrong assumption often means months of treating the wrong problem.
What’s Actually Happening
Hemorrhoids are swollen blood vessels, similar in nature to varicose veins, located in or around the anus and lower rectum. They develop when increased pressure — from straining, pregnancy, prolonged sitting, or chronic constipation — causes these vessels to enlarge.
An anal fissure is a different kind of injury entirely: a small tear in the lining of the anal canal, usually caused by the passage of a hard or large stool. The tear itself is often minor, but it triggers a cycle that keeps it from healing. Pain from the tear causes the internal anal sphincter muscle to spasm and tighten. That tightening reduces blood flow to the area, and less blood flow means the tissue struggles to repair itself. The next bowel movement reopens or aggravates the same tear, and the cycle continues. According to a clinical review published in the British Journal of Surgery, this muscle spasm and reduced blood flow — not the initial tear itself — is what typically prevents fissures from healing on their own.
Why the Symptoms Overlap
Both conditions can cause pain during or after bowel movements, bright red blood on toilet paper or in the bowl, itching or irritation around the anus, and a feeling of a lump or swelling. Because the symptom list looks so similar, people — and sometimes even a quick self-diagnosis — default to “hemorrhoid” and reach for an over-the-counter hemorrhoid cream. For hemorrhoids, that’s often reasonable. For a fissure, it usually isn’t, because standard hemorrhoid treatments don’t address the muscle spasm that’s keeping the fissure open.
A few distinctions can help tell them apart:
| Hemorrhoids | Anal Fissure | |
|---|---|---|
| Nature of the problem | Swollen blood vessel | Tear in the anal lining |
| Pain pattern | Often dull ache or pressure; can be itchy | Sharp, tearing pain, often intense during and immediately after a bowel movement |
| Visible sign | Swelling or a soft lump, sometimes protruding | A visible crack or tear, sometimes with a small skin tag nearby |
| What worsens it | Prolonged sitting, straining | Hard stool, straining, muscle tension |
This isn’t a substitute for an exam — the two conditions can also coexist — but the pain pattern is often the most useful clue. Hemorrhoid discomfort tends to be more of a persistent ache or itch, while fissure pain is typically described as sharp or tearing, concentrated tightly around the moment of a bowel movement, and slow to fade afterward.
Why the Treatment Difference Matters
This is where misdiagnosis becomes a real problem, not just a technicality. Hemorrhoid treatments are generally built around reducing swelling and soothing irritated tissue — ingredients like witch hazel, hydrocortisone, or a topical protectant. None of these address a fissure’s underlying issue: a spastic internal anal sphincter that’s cutting off blood flow to the tear.
Fissures respond best to treatment aimed specifically at relaxing that muscle. Topical calcium channel blockers, such as diltiazem, and topical nitrates, such as nitroglycerin, work by relaxing the internal sphincter directly, which restores blood flow and allows the tissue to heal. A Cochrane review and multiple randomized trials have supported topical diltiazem as an effective first-line option for chronic anal fissures, generally with a more favorable side-effect profile than nitroglycerin, which can cause headaches in a subset of patients. For readers who want a closer look at how these prescription options compare to each other and to over-the-counter alternatives, this overview of anal fissure cream options walks through the differences in more detail.
Conservative, at-home care has real evidence behind it regardless of which condition is present. Warm sitz baths, adequate fiber and fluid intake, and avoiding straining are supported first-line steps for both hemorrhoids and fissures, and a meaningful share of acute fissures heal with this approach alone. The distinction matters most when conservative care isn’t enough — that’s the point at which treating the wrong condition costs real time.
When It’s Time to See a Provider
Most rectal bleeding and pain resolve with straightforward care, but certain patterns deserve prompt medical evaluation rather than continued home treatment:
- Bleeding that is heavy, persistent, or increasing
- Pain that is severe or rapidly worsening
- A hard, painful lump that doesn’t improve (which can indicate a thrombosed hemorrhoid)
- Symptoms that persist beyond several weeks of consistent home care
- Any uncertainty about the diagnosis itself, particularly with a first episode
A brief in-person or telehealth evaluation can typically distinguish between the two conditions quickly, and it can rule out less common but more serious causes of rectal bleeding that occasionally present the same way.
The Bottom Line
Hemorrhoids and anal fissures are both common, both treatable, and both frequently confused with each other. The distinction isn’t academic — it changes what actually helps. If a “hemorrhoid” isn’t responding to standard care, or if the pain pattern feels more like a tear than a swelling, it’s worth considering that the diagnosis itself may be the problem, not the treatment.
