I apologize, but current medical regulations prohibit online diagnoses in this manner.
If it is inconvenient to visit a hospital or clinic due to the pandemic, you may consult a dermatology clinic that offers telemedicine services, which can provide you with diagnosis and treatment according to regulations.

More Info

The sudden appearance of a bump on the foreskin can be concerning, and it's important to consider various potential causes. Based on your description, there are several possibilities that could explain this symptom.
1. Pearly Penile Papules: These are small, harmless bumps that can appear around the corona of the glans penis. They are normal anatomical variations and do not require treatment.

2. Fordyce Spots: These are small, painless, pale bumps that can appear on the shaft of the penis or the foreskin. They are sebaceous glands that are not associated with any disease and are completely benign.

3. Folliculitis: This condition occurs when hair follicles become inflamed, often due to infection or irritation. It can cause small red or white bumps and may be accompanied by itching or discomfort.

4. Cysts: Sebaceous cysts can develop in the genital area, appearing as small lumps under the skin. These are usually painless and benign.

5. Infections: Sexually transmitted infections (STIs) such as herpes or genital warts can cause bumps or lesions on the genital area. If the bump is painful, itchy, or accompanied by other symptoms like discharge, it may indicate an infection that requires medical evaluation.

6. Allergic Reactions or Irritation: Sometimes, irritation from soaps, lotions, or other products can lead to localized swelling or bumps.
7. Penile Cancer: Although rare, any new growth or change in the skin of the penis should be evaluated by a healthcare professional to rule out malignancy, especially if the bump persists or changes in appearance.

Given that the bump appeared suddenly and was not present during your previous shower, it is advisable to monitor it closely. If the bump persists, changes in size or color, or if you experience any pain, discomfort, or other symptoms such as discharge or fever, you should seek medical attention promptly.
A healthcare provider will likely perform a physical examination and may ask about any additional symptoms, sexual history, and any recent changes in personal care products. Depending on the findings, they may recommend further testing or treatment options.

In conclusion, while many causes of a sudden bump on the foreskin are benign, it is essential to remain vigilant and consult a healthcare professional for an accurate diagnosis and appropriate management. Early evaluation can help alleviate concerns and ensure any necessary treatment is initiated promptly.
