Hello, generalized pruritus (itching all over the body) may be caused by allergic factors. Clinically, it most commonly manifests as urticaria or seasonal pruritus. It may also result from dry skin, allergic dermatitis, contact dermatitis, or environmental allergens. Additionally, itching can arise from bacterial or viral infections—or even fungal infections. All of these possibilities should be considered. I hope this information is helpful to you. Wishing you good health!
