Hello: It is not possible to accurately diagnose skin diseases based solely on a textual description.
If the skin symptoms do not improve or worsen, it is advisable to consult a nearby dermatologist for diagnosis and treatment.

More Info


The presence of black or dark bumps around the anus can be concerning, and it's important to understand the potential causes and implications. Based on your description, these bumps are not painful or itchy, but you have experienced some bleeding when wiping. There are several possible explanations for these symptoms, and I will outline them below.

1. Hemorrhoids: One of the most common causes of bumps around the anus is hemorrhoids, which are swollen veins in the lower rectum and anus. They can appear as lumps and may be dark in color, especially if they are thrombosed (clotted). Hemorrhoids can cause bleeding, particularly during bowel movements, and may not always be painful. If the bleeding is bright red and occurs after straining, it is often associated with hemorrhoids.

2. Skin Tags: Another possibility is the presence of skin tags, which are small, benign growths that can occur around the anal area. They are usually flesh-colored or slightly darker and are not typically associated with pain or itching. Skin tags can develop after episodes of hemorrhoids or as a result of friction or irritation.

3. Anal Warts: Caused by the human papillomavirus (HPV), anal warts can appear as small, dark bumps around the anus. They may not be painful or itchy, but they can bleed if irritated. It's important to have these evaluated by a healthcare professional, as some strains of HPV are associated with an increased risk of anal cancer.

4. Pigmented Lesions: Dark bumps can also be pigmented lesions, such as moles or other skin growths. While most are benign, any new or changing lesions should be evaluated to rule out skin cancer.

5. Fungal or Bacterial Infections: Occasionally, infections can cause changes in the skin around the anus, leading to dark spots or bumps. These may be accompanied by other symptoms, such as itching or discomfort.

6. Anal Fissures: While fissures are typically associated with sharp pain during bowel movements, they can sometimes cause bleeding. They appear as small tears in the lining of the anus and may be accompanied by bumps or tags.

Given that you have experienced bleeding, it is crucial to consult a healthcare professional for a thorough evaluation. They may perform a physical examination and possibly recommend further tests, such as a colonoscopy, to rule out any serious conditions.
In terms of management, if hemorrhoids are diagnosed, treatments may include lifestyle changes (such as increasing fiber intake and hydration), topical treatments, or in some cases, surgical options. For skin tags or warts, removal may be recommended if they cause discomfort or concern.

In conclusion, while the presence of black bumps around the anus can be benign, the occurrence of bleeding warrants a medical evaluation to ensure proper diagnosis and treatment. Early intervention can help prevent complications and provide peace of mind. Always prioritize your health and seek professional advice when you notice changes in your body.
