What kind of doctor treats Cold Urticaria?
A dermatologist, a skin doctor, often diagnoses and treats cold urticaria. An allergist, a doctor who treats allergic reactions, can also help. Most people who get hives from the cold are otherwise healthy. A direct primary care or concierge doctor can be a first stop for an evaluation and can refer you to a specialist when needed.
What is cold urticaria?
Cold urticaria is a condition in which cold air, water, or objects cause itchy hives. Hives are welts on the skin that often itch. It is also called cold contact urticaria or acquired cold urticaria. In some people, the reaction can affect the whole body.
Cold urticaria affects about 5 to 6 people in 10,000. It typically affects young adults.
Symptoms
Symptoms usually start within minutes after the skin meets the cold. In the typical form, hives appear quickly after cold exposure and go away within one hour.
- Raised, itchy, red bumps on the skin.
- A burning feeling on skin that was exposed to the cold.
- Swelling of the skin where the cold touched it.
- Swollen lips or swelling in the throat.
- Feeling lightheaded or faint.
- Shortness of breath and wheezing.
You may not get hives every time you meet something cold. Some people only get hives when they swim in cold water or have a cool wind hit their skin. Reactions that affect the whole body are more likely after a lot of cold exposure, such as swimming in cold water. In very severe cases, a drop in blood pressure, shock, collapse, and even death may occur.
Causes and who gets it
Doctors do not know what causes cold urticaria. Cold exposure makes mast cells, a type of immune cell, release histamine and other substances. This causes redness, swelling, itching, and hives. Triggers include cold air, water, objects, and even cold foods or drinks.
In primary cold urticaria, no underlying cause is found. Secondary cold urticaria is linked to other conditions, such as viral and bacterial infections, insect stings, or certain drugs or foods.
Acquired cold urticaria is a different disorder from familial cold autoinflammatory syndrome, which is a genetic condition present from infancy.
How doctors diagnose it
A doctor may suspect cold urticaria when hives or swelling appear after the skin is exposed to cold air, liquids, or objects. A cold stimulation test, which uses an ice cube applied to the skin, confirms the diagnosis. A dermatologist places a plastic bag that holds an ice cube on bare skin, usually the forearm. A hive in the shape of the ice cube that appears within 10 minutes after the ice is removed is a positive response. Even without a welt from the test, you could still have cold urticaria, so the doctor also asks questions and examines your skin.
Treatment
There is no cure for cold urticaria. Treatment includes avoiding triggers and managing symptoms. One medicine that helps many people is an oral antihistamine, which can prevent hives and itching. Omalizumab is used for people who do not respond to the other medicines for this condition.
If you ever had a serious reaction, such as passing out or swelling in your throat, your doctor may recommend that you always carry an epinephrine pen. You should carry an epinephrine auto-injector and review how to use it.
Swimming in cold water is the activity that most often causes whole-body symptoms. If you swim, first put a small area of the body, such as a hand, in the water and wait to see if symptoms appear. If your throat swells when you eat or drink anything cold, you should avoid all cold foods and drinks. Before surgery, the surgery and anesthesia teams should be told about the condition.
Cold urticaria may go away on its own. About half of the people who get it see it disappear within five years. It is also possible to have cold urticaria for life.
When to see a doctor
If you have ever felt faint or had trouble breathing when exposed to cold, it is crucial to find out if you have cold urticaria. Treatment can be especially important if you cannot go outside in winter without getting hives. Call 911 or go to the emergency room if you have trouble breathing, swelling of the lips or throat, or feel faint after cold exposure.
How a direct primary care or concierge doctor fits in
A direct primary care doctor charges a flat monthly fee instead of billing insurance, while a concierge doctor usually charges more and often works alongside insurance. A doctor in this kind of practice can explain what may trigger reactions. That doctor can also review how to use an epinephrine auto-injector.
Common questions
Can cold urticaria go away?
Yes, it can. About half of the people who get cold urticaria see it disappear within five years. It is also possible to have it for life.
Can cold urticaria cause a serious reaction?
Yes, in some people it can. Signs can include shortness of breath, wheezing, and a drop in blood pressure.
How do doctors test for cold urticaria?
Doctors test for cold urticaria with an ice cube test. A doctor places an ice cube in a plastic bag on bare skin, usually the forearm. Most people who have cold urticaria develop a welt after the bag is removed and the skin starts to warm up.
Is cold urticaria the same as familial cold autoinflammatory syndrome?
No, they are different disorders. Familial cold autoinflammatory syndrome is a genetic condition present from infancy. Unlike cold urticaria, it involves inflammation throughout the body, not just skin reactions.
