It seems that many people in the world are affected by cold and allergy. During the mornings or evenings, you tend to have sneezing along with a blocked nose. You may not know whether you are suffering from an ordinary cold or from an allergy. This is when you need to differentiate between a common cold and an allergy. The symptoms can be very similar, but they are completely different afflictions, so their treatments are also different.
Symptoms and treatments
Common symptoms might include cough, fatigue, sneezing, sore throat, running nose, stuffy nose. Usually aches, pain, fever, and thick yellow/greenish nasal discharge aren’t an indication of allergies just as itchy eyes don’t indicate a cold.
· Colds are caused by viruses. Their treatments are usually rest, pain relievers, decongestants, over-the-counter medications.
· Allergies are immune system responses triggered by one or more specific allergen. The best things you can do is to avoid the exposure to allergens if possible. Treatments of seasonal allergies are antihistamines (prescription or over-the-counter), decongestants, nasal steroid sprays.
What is cold allergy ?
Cold allergy, Cold Urticaria or cold hives is an allergy. This kind of allergy affects the skin, causing hives (urticaria) or red welts to form on the skin due to the exposure to a cold stimulus. The hives are usually itchy. Most often they show up on the hands and feet where they can cause swelling as well. When hives form, the fluid from the capillaries flows out into the surrounding tissues causing them to swell up. Hives come in different sizes. If the disease becomes chronic the hives can last for weeks. The Cold Urticaria can be inherited or caught.
What are the symptoms of Cold Urticaria?
When the body is exposed to the cold, hives occur on the skin on the affected area. Hives usually last from a few minutes to a few days. You usually get an irritating, burning sensation through your skin as if bees are stinging you. Severe reaction, when the hives form very fast, usually within less than 3 minutes of exposure, can be life-threatening (anaphylactic shock).
How to diagnose Cold allergy?
The allergist performs a cold test. During the procedure a piece of ice is held against the forearm usually for 2-3 minutes. The result is positive if red hives are raised on the contacted area.
How to Treat Cold Hives
The most important treatment is to stay warm. To control the condition, you should avoid exposure to cold temperatures or warm up immediately after the exposure. Hot water on the affected area or a warmer environment does not improve the condition, but helps prevent it from worsening. If the hives already formed, the warming up afterwards may cause the hives to go away faster.
According to some home remedies some vegetable shortening or butter applied on the affected area may reduce the risk of eruption of the hives. Good idea here would be to reduce the inflammation in your body. Usually, the doctors prescribe Antihistamines. Topical antihistamine creams may also provide some temporary relief.
Some studies suggest that Cold Urticaria has been linked to a gluten intolerance and gluten free diets have helped some Cold Urticaria sufferers. Hives formation is also assumed to be due to food allergies, asthma, environmental changes, and eczema.
The causes of hives are still under investigation.
