His whole body was itchy, he thought it was an allergy but then he was diagnosed

Most cases of hives don’t need treatment because the rash usually disappears within 24 hours. However, if symptoms continue, a doctor may recommend antihistamines, steroid medications, or menthol-based creams to help reduce itching and discomfort.

People with allergies are more prone to developing hives. They can also occur as a reaction to certain medications or after contact with an allergen you may not have recognized, such as specific foods, pollen, or environmental substances. Additionally, when you’re ill or managing another medical condition, your body may be more sensitive, making hives more likely to appear.
