Hemorrhoids or anal fistula?


I am a high school student, and about a year ago, I experienced blood in my stool once or twice, but it resolved within a day or two.
Since then, I have not had any episodes of blood in my stool.
Recently, I noticed a soft protrusion near my anus when I go to the bathroom; sometimes it disappears right after I finish, and other times it takes a few hours to go away.
It is not painful, and there is no blood in my stool.
I have bowel movements every one to two days, and the amount is not very large.
Additionally, I have been feeling a slight sensation near my buttocks, which is not pain but feels somewhat like a pulsing sensation, occurring intermittently.
I am unsure what this could be and am quite worried, although it hasn't affected my daily life.
I would like to ask for a doctor's opinion.

The diagnosis of anal diseases includes not only the medical history but also visual inspection, palpation, and even endoscopic examinations (colonoscopy, sigmoidoscopy, or anoscopy).
Therefore, please seek a nearby colorectal specialist for diagnosis and treatment (attached is a list of specialists).

Understanding the differences between hemorrhoids and anal fistulas is crucial, especially for someone like you who is experiencing symptoms that could be related to either condition. Let's break down both issues to help you understand what might be happening.

Hemorrhoids are swollen veins in the lower rectum and anus, similar to varicose veins. They can be internal (inside the rectum) or external (under the skin around the anus). Common symptoms of hemorrhoids include:
- Bleeding: This usually occurs during bowel movements and can be seen on toilet paper or in the toilet bowl.

- Swelling or a lump: You mentioned feeling a soft lump near your anus, which could be a hemorrhoid, especially if it appears and disappears.

- Discomfort or itching: While you noted that you don’t feel pain, some people experience itching or a sensation of fullness.

The fact that you had blood in your stool a year ago but have not experienced it since is a positive sign. Hemorrhoids can often resolve on their own, especially if they are not causing significant discomfort.

Anal fistulas, on the other hand, are small tunnels that develop between the end of the bowel and the skin near the anus. They often occur after an abscess (a collection of pus) forms in the anal area. Symptoms of anal fistulas can include:
- Pain: This is often more severe than with hemorrhoids, especially during bowel movements.

- Discharge: You might notice pus or blood leaking from the opening of the fistula.

- Swelling or irritation: Similar to hemorrhoids, but usually more persistent.

Given your description, it seems less likely that you have an anal fistula, especially since you are not experiencing pain or discharge. The soft lump you feel could very well be a hemorrhoid, particularly if it appears and disappears and is not causing you significant discomfort.

What to Do Next:
1. Monitor Your Symptoms: Keep an eye on the lump and any changes in your bowel habits. If it becomes painful, starts to bleed, or if you notice any discharge, it’s important to seek medical attention.

2. Dietary Changes: Ensure you are eating a high-fiber diet to help soften your stools and reduce straining during bowel movements, which can aggravate hemorrhoids.

3. Hydration: Drink plenty of water to help keep your stools soft.

4. Consult a Healthcare Provider: If the lump persists or if you have any concerns, it’s best to consult a healthcare professional. They can perform a physical examination and provide a definitive diagnosis.

5. Avoid Straining: When using the bathroom, try not to strain, as this can worsen hemorrhoids.

In conclusion, while your symptoms may suggest hemorrhoids, it’s essential to keep monitoring your condition and consult a healthcare provider if you have any concerns. Early intervention can help prevent complications and ensure that you maintain your health and well-being. Remember, it’s always better to seek advice from a medical professional when it comes to health concerns, especially those involving sensitive areas like the rectum and anus.
