What are the Causes for itchy bumps?

Itchy bumps can be caused by various factors, including allergic reactions to substances like foods, medications, or insect bites. Skin conditions such as eczema, hives, or psoriasis may also lead to the development of itchy bumps. Additionally, infections like chickenpox or folliculitis can result in similar symptoms. Environmental irritants, such as certain fabrics or chemicals, can further exacerbate the itchiness.
