Why is it itching after a few handfuls are swollen?

A swollen and itchy penis may be caused by contact dermatitis, fungal infection, allergic reaction, balanitis, or pubic lice, and can be relieved by topical cleansing, antifungals, antihistamines, antibiotic treatments, or insecticide treatments.

1. Contact dermatitis:

Contact with detergents, low-quality condoms or underwear materials may trigger an inflammatory reaction in the skin. It manifests as local redness, swelling, itching and tiny papules. The symptoms usually subside on their own in 3-5 days after avoiding scratching. It is recommended to suspend the use of suspected contact items, wash them with warm water and keep them dry. In severe cases, weak hormone ointments can be used for short-term external use.

2. Fungal infection:

Candida albicans infection is common in people with excessive foreskin, and humid environment can easily lead to bacterial flora imbalance. Typical symptoms are annular erythema with white discharge, and itching worsens at night. Clotrimazole cream or miconazole powder can effectively inhibit fungal reproduction. At the same time, the foreskin needs to be washed daily and dried thoroughly.

3. Allergic reaction:

Acute allergies may be triggered by eating seafood or taking sulfa drugs. It is characterized by sudden edema with an urticaria-like rash, which may affect urination in severe cases. Oral antihistamines such as loratadine can relieve symptoms, but allergens need to be checked to avoid further exposure.

4. Balanitis:

Inflammation caused by bacterial infection is common in people with poor hygiene and manifests as congestion, erosion and yellow purulent secretions in the inner plate of the foreskin. Soaking in potassium permanganate solution combined with erythromycin ointment can control the infection. If recurrence occurs, circumcision surgery should be considered.

5. Pubic lice parasitism:

Parasite bites can cause severe itching, and gray-white worm bodies and rust-colored eggs can be seen with the naked eye. After shaving the pubic hair, use 100% tincture or permethrin to treat it, and all underwear must be washed in boiling water. Sexual partners need to be treated simultaneously to prevent cross-infection.

You should choose pure cotton breathable underwear every day to avoid friction, and avoid eating spicy and irritating foods. Wash your vulva with warm water every day and dry it completely. Avoid using alkaline shower gels. If symptoms last for more than a week, ulcers or fever appear, timely medical attention is required. People with diabetes need to be more vigilant about the spread of infection. Pay attention to cleanliness before and after regular sexual intercourse. People with excessive foreskin can consult a doctor to evaluate the necessity of surgery. Maintain moderate exercise to enhance immunity, but strenuous exercise should be suspended during an attack to reduce local irritation.
