The most common symptom of hemorrhoids is bright red blood on toilet paper or in the toilet bowl after a bowel movement. Beyond bleeding, symptoms depend on whether the hemorrhoid is internal (inside the rectum) or external (under the skin around the anus), and the two types feel quite different.
Internal Hemorrhoid Symptoms
Internal hemorrhoids form inside the rectum, where there are fewer pain-sensing nerves. That means they’re often painless, even when they bleed. You might not know you have one until you notice a few drops of bright red blood on your toilet tissue or dripping into the bowl. The blood is typically separate from the stool itself and is noticeable because of its vivid red color.
Internal hemorrhoids are classified by how far they protrude from the rectum. A grade I hemorrhoid stays inside and usually causes no symptoms beyond occasional bleeding. A grade II hemorrhoid bulges out during a bowel movement but slides back in on its own. Grade III hemorrhoids push out and need to be gently pressed back in with a finger. At this stage, you’re more likely to notice itching and minor stool leakage on your underwear. A grade IV hemorrhoid stays outside the rectum permanently and can develop chronic irritation and swelling.
Painless bleeding can happen at any grade. Many people first discover internal hemorrhoids only because they see blood and assume something more serious is going on.
External Hemorrhoid Symptoms
External hemorrhoids sit under the skin around the anus, where nerve endings are plentiful. They tend to be more uncomfortable than internal ones. Common symptoms include:
- Itching or irritation around the anus
- Pain or tenderness, especially when sitting
- Swelling you can feel as a lump near the anus
- Bleeding during or after bowel movements
Large external hemorrhoids can make it difficult to clean the area thoroughly after using the bathroom. Leftover stool irritates the surrounding skin, which creates a cycle of itching, wiping, and more irritation. This is one of the main reasons hemorrhoids cause persistent anal itch.
Thrombosed Hemorrhoids
Sometimes blood pools inside an external hemorrhoid and forms a clot. This is called a thrombosed hemorrhoid, and it’s the most painful form. You’ll typically notice a firm, purple-blue lump on or near the anus that you can see or feel. It can cause severe pain when sitting, walking, or having a bowel movement.
The pain is usually most intense in the first 48 hours. After that, the clot gradually begins to break down and the swelling recedes over one to two weeks. If the pain is unbearable in those early hours, a doctor can remove the clot through a quick in-office procedure that provides almost immediate relief.
What Hemorrhoid Bleeding Looks Like
Hemorrhoid blood is characteristically bright red. You’ll see it on the toilet paper, on the surface of your stool, or as a few drops in the water. It usually appears only during or right after a bowel movement and stops on its own. The amount is typically small.
This matters because blood color and pattern help distinguish hemorrhoids from more serious conditions. Darker blood, blood mixed into the stool rather than sitting on top, or bleeding that persists between bowel movements can point to something other than hemorrhoids and warrants a medical evaluation.
Hemorrhoids vs. Similar Conditions
Several conditions share symptoms with hemorrhoids, which is why self-diagnosis can be unreliable.
Anal fissures (small tears in the lining of the anus) also cause bleeding, but they’re more likely to produce sharp, stinging pain during and after a bowel movement. Hemorrhoids, by contrast, are often painless or cause a duller discomfort. If your primary symptom is a burning or tearing sensation while you go, a fissure is the more likely cause.
Colorectal cancer can also cause rectal bleeding, but the pattern is different. Cancer-related bleeding tends to be more persistent, and the blood may be darker. It also comes with symptoms hemorrhoids don’t typically cause: persistent changes in bowel habits (new diarrhea or constipation that doesn’t resolve), abdominal cramping, a feeling that you can’t fully empty your bowel, unexplained weight loss, or unusual fatigue. Adults over 50 and anyone with these additional symptoms should get evaluated promptly rather than assuming hemorrhoids are the explanation.
How Hemorrhoids Are Diagnosed
If you visit a doctor about your symptoms, the exam is straightforward. For external hemorrhoids, a visual check is often enough. To evaluate internal hemorrhoids, the doctor performs a digital rectal exam, inserting a gloved, lubricated finger into the anus to feel for swollen tissue.
If more detail is needed, the next step is an anoscopy. A short, lighted tube about two inches long is inserted into the anus to give the doctor a direct view of the lower rectum. The procedure takes only a few minutes and doesn’t require sedation. It’s the most reliable way to confirm internal hemorrhoids, rule out fissures, and check for anything unusual that might need further testing.
Warning Signs That Need Urgent Attention
Most hemorrhoid symptoms are manageable and resolve with basic home care. But large amounts of rectal bleeding, especially if accompanied by lightheadedness, dizziness, or feeling faint, require emergency care. These symptoms can signal significant blood loss or a condition unrelated to hemorrhoids that needs immediate evaluation.
