Psoriasis on the ears (Psoriasis) can be controlled but not completely cured. Use a mild topical treatment like Mometasone or a combination with salicylic acid as advised, and keep the area moisturized with a gentle emollient. Avoid scratching or using harsh ear buds. Since the ear is a sensitive area, it?s best to consult a dermatologist for the right strength medicine and safe long-term management.

Moist, itchy blisters on the hands can be due to Dyshidrotic eczema. Keep hands dry, avoid frequent soap/detergents, and use a thick moisturizer regularly. Avoid scratching and wear gloves when using water or chemicals. If it keeps recurring or worsens, consult a dermatologist for proper management.

Skin problems after Typhoid fever can occur due to weakness, dryness, or post-infection reactions, sometimes causing rashes, itching, or pigmentation. Keep the skin clean, use a good moisturizer regularly, and avoid harsh soaps or scratching. Eat a healthy diet to support recovery. If the skin issue persists, spreads, or worsens, consult a doctor to rule out infection or other causes.

Cracked, hard skin on fingers is usually due to dryness or Hand dermatitis. Keep your hands well moisturized by applying a thick cream or petroleum jelly several times a day, especially after washing, and avoid harsh soaps or frequent exposure to water and detergents (use gloves if needed). You can use a gentle healing cream like Urea cream at night to soften the skin. If there is pain, bleeding, or no improvement, consult a doctor for proper treatment.

A long-standing swelling or growth on the leg for 2 years with itching is not likely a simple skin problem, it could be something like a chronic infection, scar tissue such as Keloid, or another skin condition, so it should not be treated with random creams. Avoid using multiple products; keep the area clean and do not scratch. You may use a mild soothing cream or moisturizer for itching, but the most important step is to consult a dermatologist or surgeon for proper examination (and possibly tests/biopsy) to confirm the cause and get the right treatment.
