Itching around the anus with a sensation of a foreign body?


Hello Doctor: For the past two days, I've been experiencing itching in the area between the anus and the vaginal opening.
When I wash, I can feel a lump just below the anus, close to the vaginal opening, and there are small bumps beneath that lump.
However, there is no pain.
I have a history of constipation, but I do not feel discomfort during bowel movements, and there has been no bleeding—just occasional itching over the past few days.
Additionally, today I've had a persistent feeling of incomplete urination.
I'm not sure if these issues are related.
Currently, I am abroad and it's inconvenient to seek medical attention.
I've been researching online but I'm uncertain about what the problem might be.
I have taken photos but I don't know how to share them.
I hope to receive a response from the doctor.
Thank you!

This situation is likely a small external hemorrhoid.
If there is no bleeding or pain, it can be monitored.
During this period, it is advisable to avoid constipation and shorten the time spent on bowel movements.
Increasing fiber intake can also be helpful.
Warm sitz baths should aid in alleviating symptoms.
If convenient, you can also purchase hemorrhoid suppositories at the pharmacy.

More Info


Itchy anus and the presence of unidentified bumps in the perianal area can be concerning symptoms that warrant careful consideration. Based on the symptoms you've described, there are several potential causes that could explain your discomfort and the bumps you've noticed.

1. Hemorrhoids: One of the most common causes of itching and bumps around the anus is hemorrhoids. These are swollen blood vessels in the rectal area that can cause discomfort, itching, and sometimes bleeding. They can be internal or external, with external hemorrhoids often presenting as lumps around the anal opening. Constipation can exacerbate this condition, as straining during bowel movements can increase pressure on these vessels.

2. Skin Irritation: Irritation from hygiene products, soaps, or even excessive cleaning can lead to itching and discomfort. The skin in the anal area is sensitive, and using harsh soaps or wipes can disrupt the natural barrier, leading to irritation and itching.

3. Fungal or Yeast Infections: Fungal infections, particularly candidiasis, can cause itching and discomfort in the genital and anal areas. These infections can lead to the development of bumps or rashes, especially in warm, moist environments.

4. Anal Warts: Caused by the human papillomavirus (HPV), anal warts can appear as small bumps around the anus. They are usually painless but can cause itching or discomfort. If you suspect this, it is important to consult a healthcare provider for diagnosis and potential treatment.

5. Skin Conditions: Conditions such as psoriasis or eczema can also affect the anal area, leading to itching and the formation of bumps. These conditions often require specific treatments to manage symptoms effectively.

6. Pinworms: Particularly in children, pinworm infections can cause significant itching around the anus, especially at night. While this is less common in adults, it is still a possibility worth considering if you have been experiencing intense itching.

7. Other Infections: Bacterial infections or sexually transmitted infections (STIs) can also lead to symptoms in the genital and anal areas, including itching and the formation of bumps. If you have had any recent sexual activity, this could be a consideration.

Given your symptoms of itching, the presence of bumps, and the sensation of incomplete urination, it is advisable to seek medical attention as soon as possible. While you mentioned that you are currently abroad and finding it difficult to see a doctor, it is essential to prioritize your health. If you can, try to find a local healthcare provider who can examine you in person. They may perform a physical examination and possibly recommend tests to determine the exact cause of your symptoms.

In the meantime, here are some general tips to alleviate discomfort:
- Maintain Hygiene: Keep the area clean and dry. Use mild soap and avoid harsh chemicals.

- Avoid Irritants: Stay away from scented products or wipes that may irritate the skin.

- Warm Baths: Soaking in warm water can help soothe itching and discomfort.

- Over-the-Counter Treatments: Consider using over-the-counter creams or ointments designed for hemorrhoids or itching, but consult a pharmacist if you're unsure.

In conclusion, while there are several potential causes for your symptoms, a proper diagnosis from a healthcare professional is crucial for effective treatment. Do not hesitate to seek medical help, as timely intervention can prevent complications and improve your quality of life.
