The itching and rash may be due to skin irritation or an allergic reaction caused by the smoke or chemicals released from the burned All Out flash card. Some people develop redness, small bumps, or a burning sensation when the skin comes in contact with chemical fumes, especially if they already have sensitive skin or allergies. Wash the affected area gently with plain water and a mild soap to remove any remaining irritants. Avoid scratching the rash, as this can worsen irritation and increase the risk of infection. Wearing loose cotton clothes and staying in a well-ventilated area may also help reduce discomfort. Try not to apply strong creams, perfumes, or home remedies on the rash. If the itching or rash becomes severe, a doctor may advise suitable treatment. Seek medical care quickly if you develop swelling of the face, breathing difficulty, severe burning, blisters, fever, or if the rash keeps spreading despite basic care.
