Repeated runny nose, along with itching of the hands and legs, is most commonly due to an allergic condition. Your body may be reacting to triggers like dust, pollution, weather changes, certain foods, or animal allergens, which can cause both nasal symptoms and skin itching. The fact that it happens in a similar pattern each time suggests an ongoing sensitivity rather than a one-time illness. Allergy symptoms tend to come back if the trigger is still present or not identified. Medicines can help control symptoms, but they should be used only if advised by your doctor, especially if the problem keeps recurring. Long-term relief depends more on identifying and avoiding the cause rather than just taking treatment each time. To prevent this, try to notice what triggers your symptoms. Keep your surroundings clean, avoid dust exposure, wear a mask if needed, and wash your hands and face after coming in from outside. Wearing loose cotton clothes and keeping skin moisturised can reduce itching. If symptoms are frequent or severe, a doctor may recommend proper allergy testing or a long-term management plan.
