Hives (urticaria) are skin welts that are itchy and raised. They occasionally sting or hurt and are generally colored red, pink, or flesh. Hives are usually the result of an allergic reaction. But although they are commonly linked to allergic reactions, hives can also be brought about by stress, insect bites, medications, cold temperatures, sunlight, infections, and other underlying illnesses.
It’s essential to determine what caused the rash. Knowing the trigger will help you avoid it and stop additional hives from developing. Hives may disappear after 24 hours of first emerging. If hives need to be treated, anti-inflammatory medications or immune system suppressants can be used. But people frequently treat hives at home without obtaining additional medical care or assistance.
Most hive cases go away on their own within a few minutes or hours of first appearing. However, if you feel lightheaded, your face or throat starts to swell, or you have trouble breathing, you should visit a doctor immediately. These could be symptoms of an allergic reaction that needs immediate medical attention.
Your skin may feel less irritated if you apply something cool, such as a cold compress. Apply ice or a bag of frozen vegetables to the area affected by wrapping them in a towel for 10 minutes. Repeat as necessary throughout the day. Ice can help stop bleeding and reduce swelling and irritation.
The cold reduces blood flow, which in turn might lessen discomfort. Additionally, it can alleviate any bruising. In case of an emergency, you should store immediate cold packs in the car or your home’s first aid box. Chemicals in instant cold packs are activated when the pack is squeezed. Cold compresses should be used for at most 20 minutes.
A 20-minute on period followed by a 20-minute off period is recommended. If additional time is required, you can continue to ice. There is no predetermined length of time after which you must halt. However, if your condition doesn’t improve within 48 to 72 hours, you should schedule a visit with the doctor.
