Ringworm on the hand is a fungal skin infection that commonly causes round or ring-shaped patches with redness, itching, scaling, or slightly raised borders. Children may spread the infection through scratching, sharing towels, contact with infected people, pets, or sweaty clothing. Warm weather and moisture can also make the infection spread more easily. Treatment usually focuses on controlling the fungus and keeping the skin dry and clean. Antifungal creams such as clotrimazole, luliconazole, terbinafine, or ketoconazole are commonly used and are usually applied over the affected area and a small surrounding margin regularly for the advised duration. Washing hands properly, avoiding scratching, using separate towels, and keeping the area dry may help prevent spread to other body parts or family members. Steroid-containing creams may temporarily reduce redness, but can sometimes make ringworm harder to clear completely. Multiple spreading patches, pus formation, pain, or infection involving nails or scalp may need longer treatment or oral antifungal medicines.

Red colored marks on the hands and back can be caused by an allergy, fungal infection, eczema, heat rash, insect bites, dry skin, psoriasis, or irritation from soaps, chemicals, sweat, or clothing. Some marks may appear flat and mild, while others can become itchy, scaly, or spread slowly over time, depending on the cause. Treatment usually depends on whether the marks are itchy, painful, dry, ring-shaped, or spreading. Moisturisers and gentle skin care may help if dryness or irritation is the main problem, while antifungal or anti-allergy treatment may be needed in some cases. Avoid scratching the area repeatedly because this can increase redness and dark marks. Using mild soaps, keeping the skin clean, and avoiding harsh chemicals or excessive sweating may also help reduce irritation. If the marks continue increasing, become painful, develop scaling or pus, or do not improve after basic care, the skin condition may need closer examination to identify the exact cause and choose the right treatment.
