The primary reasons for itchy legs commonly include dry skin, bug bites, allergies, skin conditions like eczema or psoriasis, irritation from shaving, and more serious health issues such as diabetes, kidney or liver disease, and nerve damage. Dry skin is a major cause and can be triggered by weather, harsh soaps, dehydration, or skin conditions that dry out the skin and cause itching and flaking. Bug bites and contact with irritating plants also cause localized itching. Allergic reactions to skincare products or environmental allergens can cause red, itchy rashes on the legs. Certain chronic skin disorders such as eczema and psoriasis lead to persistent itching and inflammation. Shaving can cause irritation, razor bumps, or ingrown hairs that itch as well. Itchy legs can sometimes signal underlying health problems including diabetes (due to poor circulation or nerve damage), kidney or liver disease, or even exercise-induced histamine release and increased blood flow. Stress can also aggravate itching. If itching persists or worsens, consulting a healthcare professional is advisable for diagnosis and treatment.
