Hives Wheels

Hives wheels are reddish, whitish, or skin colored raised welts that appear on the surface of the skin. Hives wheels develop on the skin when histamine and other chemicals are released into the blood stream causing the leakage of fluid under the skin leading to swelling and the characteristic raised welts of hives. Hives wheels can pop up for no apparent reason and disappear without any form of treatment. Factors such as stress level, emotional wellbeing, heat, cold, sweat, and sun can all cause a case of hive wheels. Because these factors are somewhat immeasurable it is likely that most people who suffer from acute attacks of hives will never know what caused them.

 

Urticaria Welts and Food

 

Hives can also be directly linked to allergies. For example, people who suffer from hay fever are also more susceptible to urticaria welts. If you suspect that your hives are being caused by a food allergy or reaction you can try a low histamine diet. Histamines occur in food naturally, and particularly in fermented foods when, during fermentation, the amino acid histidine is converted to histamine. Examples of foods that are high in histamines due to fermentation are cheeses, sausage, fermented soy products, fermented alcoholic beverages such as wine and beer, and vinegar. According to Jeffrey Tulin-Silver, M.D. and Suchetha Kinhal, M.D., high amounts of histamines occur naturally in eggplant, spinach, mushrooms, tomatoes, and finfish. Additionally, eggs, strawberries, tomatoes, fish, shellfish, chocolate, bananas, pineapple, papaya, chocolate, strawberries, milk, and fermented alcoholic drinks release histamine directly from mast cells. In addition to avoiding foods that may contain histamines it is likely your allergist will put you on a restricted diet if an allergy test has been administered and certain foods are suspected to cause allergies or intolerance.

 

Hives Wheels – What You Can Do About Them

 

Acute cases of hives wheels can be treated with over the counter remedies with the goal of reducing the release of histamines (antihistamines such as Benadryl and Claritin), alleviating itchiness, and reducing swelling. For mild cases of hives cool baths/showers and compresses can help as can keeping the skin moisturized with a lotion formulated for sensitive skin. For individuals who suffer from chronic hives (those that last longer than six weeks sometimes up to several years) researchers at the University of Nebraska Medical Center have found that vitamin D supplements can significantly reduce chronic hives and alleviate the symptoms. Researchers found that nearly half of the patients observed who suffered from chronic hives also had low vitamin D levels. The recommended dose is a supplement of 1,000 to 2,000 international units (IU) per day.


Hives That Come and Go

Hives that come and go over extended periods of time are considered to be chronic hives. All forms of hives, both chronic and acute can come in waves making them appear to spread from one body part to the next or clear and then return. Hives that come and go are thus common and are a telltale sign of this type of rash. Patients should keep in mind however, while a case of hives can last anywhere from an hour to several weeks, individual urticaria welts should not last for more than 24 hours.

 

Hives That Come and Go: Chronic Hives

 

Hives are considered chronic when any given episode lasts for more than six weeks. Unlike acute cases of hives that are usually caused by an allergy to foods, food additives, medication, or stings and bites, chronic hives tend to be without a known origin and are termed idiopathic urticaria. In 50% of these cases the urticaria welts are cause by a histamine reaction within the body resulting in the itchy red welts. In other cases of idiopathic urticaria immune or hormonal functions are to blame and often point towards an infection or disease unrelated to the skin and allergies. In some rare cases of chronic hives welts may last longer than 24 hours causing pain rather than the common itching. When the welts clear they can leave a bruise on the skin. While not all cases of painful hives are caused by vasculitis (inflammation of the blood vessels, http://www.mayoclinic.com/health/vasculitis/DS00513), it is the most common cause of this form of hives.

 

Dealing with Hives That Come and Go

 

If you suffer from hives that come and go for more than six weeks you should book an appointment with your allergist or an immunologist so that a series of tests can be run to discover possible causes including any underlying illness. When you visit your doctor it is important to share with him/her your full family medical history, any medications (including vitamins) you are taking, and information about your home and work environment, including the products used in those places. Depending on your particular case a series of test may be necessary. Your allergist may recommend a skin allergy test to determine if you are coming into contact with or ingesting an allergen. Other test may include a skin biopsy, to determine if you have vasculitis, and blood and urine samples. As frustrating as it may seem only 20% of hives cases can be diagnosed with a cause, making patient comfort and itchiness relief the primary treatment. Anti-histamines, steroids, and topical creams are often the best method to treat hives.
