Based on the description of your symptoms, it seems that several conditions could potentially be causing your itching: scabies, fungal infections, eczema, or even psoriasis are plausible. Considering you have itching that worsens at night, especially between the fingers, scabies should be highly considered. Scabies is caused by mites that burrow into the skin, leading to intense itching and a rash. Another potential cause could be a fungal infection, such as tinea cruris (jock itch), which thrives in warm, moist areas and might explain the itching around your foreskin and buttocks, particularly given the sweating you mentioned.
Eczema could also cause similar features, especially with dry, rough, thick, and scaly patches. Psoriasis, although less common in these areas, could cause scaly skin that might look whitish or flaky. However, a definitive diagnosis would require a physical examination and possibly some skin tests (like a skin scraping or biopsy) by a healthcare professional.
For management at home, it would be safe to keep the affected areas clean and dry to reduce moisture accumulation, which could worsen symptoms. Avoid scratching, as this can lead to further irritation and potential infection. Over-the-counter hydrocortisone cream might provide temporary relief for itching, but cautious use is advised as it may not be suitable for certain infections. If scabies is suspected, permethrin cream is commonly used, but it requires a prescription.
Also, for any potential fungal infections, antifungal creams could be beneficial, but again, it’d be best to get a definitive diagnosis before self-treating. Due to the severity and progression of your symptoms, consulting with healthcare professional as soon as possible would be critical. They can guide you through appropriate treatment and ensure you’re not dealing with a condition that needs urgent care. If any signs of a secondary bacterial infection arise (e.g., increased redness, swelling, or pus), immediate medical attention would be necessary.
