Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. Dear hives are usually temporary in nature, wherein the allergic reaction induces a short-lived rash that resolves once the allergen is removed from the environment. The most common example is this regard is that of the Poison Ivy rash. Another common example of allergic rash is hives. This rash can be very itchy, and it has a typical pattern. Usually referred to as Urticaria, hives appear in the form of reddened disc-like patches that can appear anywhere on the body, but are more common in the upper half of the body.Ringworm is a common fungal rash that has a circular pattern, with some degree of pustules along the outer circumference. The red patches here might have a raised border. Hope I have answered your query. Let me know if I can assist you further.
