Itching at the base of the scrotum near the anal area?


Hello doctor, as mentioned in the subject, sometimes after straining during a bowel movement, I experience sudden itching.
Upon touching, I found a swollen vein from the base of the scrotum to near the anus.
What could this symptom be? Thank you.

During the hot summer months, patients may experience symptoms of itching in the perineal area.
It is recommended to wear loose-fitting pants, avoid prolonged sitting, and keep the perineal area cool and well-ventilated to help improve the condition.
If you notice something that feels like a cord, it is advisable to consult a urologist for examination if you have concerns.

More Info


Itchy sensations in the area from the scrotum to the anus can be uncomfortable and concerning. There are several potential causes for this symptom, and understanding them can help in determining the appropriate treatment or management strategies.

1. Skin Irritation or Allergies: One of the most common causes of itching in the genital area is skin irritation. This can be due to various factors such as sweat, moisture, friction from clothing, or allergic reactions to soaps, detergents, or personal hygiene products. If you have recently changed any products you use, consider reverting to your previous ones to see if the itching subsides.

2. Infections: Fungal infections, such as jock itch (tinea cruris), can cause itching and irritation in the groin area. This is particularly common in warm, moist environments. Bacterial infections can also occur, especially if there is any break in the skin. Additionally, sexually transmitted infections (STIs) can lead to similar symptoms, so it is essential to consider your sexual health history.

3. Hemorrhoids or Anal Fissures: If you experience itching after bowel movements, it could be related to hemorrhoids or anal fissures. Hemorrhoids can cause swelling and discomfort, leading to itching, while anal fissures can cause pain and irritation during and after bowel movements.

4. Dermatological Conditions: Conditions such as psoriasis or eczema can also affect the genital area, leading to itching and discomfort. These conditions may require specific treatments, including topical steroids or other medications.

5. Hygiene Practices: Inadequate hygiene can lead to the accumulation of sweat and bacteria, resulting in itching. Conversely, excessive washing or using harsh soaps can strip the skin of its natural oils, leading to dryness and irritation.

6. Underlying Medical Conditions: Certain medical conditions, such as diabetes or liver disease, can lead to generalized itching, including in the genital area. If you have other symptoms or a history of such conditions, it may be worth discussing with your healthcare provider.


Solutions and Recommendations:
- Maintain Good Hygiene: Ensure that the area is clean and dry. Use mild, unscented soaps and avoid harsh chemicals. After bathing, make sure to dry the area thoroughly.

- Wear Loose-Fitting Clothing: Opt for breathable fabrics like cotton to reduce moisture and friction. Avoid tight underwear that can exacerbate irritation.

- Topical Treatments: Over-the-counter antifungal creams may be helpful if a fungal infection is suspected. For skin irritation, hydrocortisone cream can reduce inflammation and itching.

- Avoid Scratching: While it may be tempting, scratching can worsen the irritation and lead to secondary infections.

- Consult a Healthcare Provider: If the itching persists, worsens, or is accompanied by other symptoms (such as discharge, pain, or changes in bowel habits), it is crucial to seek medical advice. A healthcare provider can perform a physical examination and may recommend tests to determine the underlying cause.

- Consider Dietary and Lifestyle Changes: If you suspect that moisture or sweat is contributing to the problem, consider dietary changes that may reduce sweating or increase hydration. Staying well-hydrated can help maintain skin health.

In summary, while itchy sensations from the scrotum to the anus can arise from various causes, understanding the underlying factors is essential for effective management. If self-care measures do not alleviate the symptoms, or if you notice any concerning changes, do not hesitate to reach out to a healthcare professional for further evaluation and treatment.
