Chronic urticaria can last for several months and often needs regular antihistamines for a longer period under medical supervision. Your doctor may adjust the dose, add other medicines, or check for triggers such as foods, infections, stress, or autoimmune causes. If symptoms persist, consult a dermatologist or allergy specialist, who may prescribe treatments such as biologics or immunosuppressants to achieve better long-term control.

Hives that last for more than six weeks are called chronic urticaria and may not always be caused by food allergies, even if allergy tests are normal. Continue taking your prescribed antiallergic medication and try to avoid possible triggers such as stress, heat, infections, or certain medicines like painkillers. If your hives persist, consult a dermatologist or an allergy specialist for further evaluation and possible adjustment of treatment.

A frequent runny nose is often caused by allergies, dust, pollution, or a common cold. Try to avoid triggers that worsen your symptoms and keep your home environment clean. You may use an over-the-counter antihistamine or a saline nasal spray to help relieve symptoms. If the problem persists or is accompanied by sneezing, itching, or sinus discomfort, please consult your doctor for proper evaluation and treatment.

Get plenty of rest and drink warm fluids to stay hydrated. You may take paracetamol to lower your fever and relieve discomfort. Try steam inhalation or saline nasal drops to ease a runny nose. If your symptoms last more than a few days, get worse, or you have trouble breathing, please consult your doctor.
