Scabies spreads easily through close skin contact, shared bedding, towels, and clothing, so it is common for the whole family to develop itching and rashes together. The itching is usually worse at night and may affect the fingers, waist, underarms, groin, wrists, and other body folds. Even if one person improves, reinfection can happen if all affected family members are not treated at the same time. Doctors commonly advise anti-scabies lotions or creams for all household members together, even if some people have only mild symptoms. Clothes, bedsheets, towels, and blankets should be washed properly in hot water and dried well because mites may survive on fabrics for a short time. Nails should be kept short, and scratching should be minimised to avoid skin infection and irritation. Itching may continue for some time even after successful treatment because the skin remains sensitive temporarily. Avoid sharing towels, clothes, or bedding during recovery. Repeated use of strong steroid creams without proper guidance may worsen the condition or hide active infection. Consult a doctor if itching continues for many weeks, pus develops, swelling increases, or new rashes keep appearing despite proper treatment and hygiene measures.

These symptoms, especially itching across your body and bumps on the penis, could indicate conditions like scabies, a fungal infection, or contact dermatitis. Because treatments differ significantly, it is crucial to avoid self-medicating with random creams, which can worsen the irritation. A doctor may prescribe permethrin cream for scabies or antifungal/mild steroid creams for other rashes, depending on the diagnosis. Please consult a dermatologist or general practitioner for an in-person examination. Meanwhile, keep the skin clean and dry, and avoid scratching to prevent a secondary bacterial infection.
