Hives on the skin (clinically called urticaria) can be identified by raised skin and rashes. It can appear on only one area or spread across large areas of the body. The rash can be extremely itchy and typically range from a few millimetres to the size of a person’s hand.
Read on to learn about the different hives types and at-home remedies that can help alleviate symptoms of the condition.
What are the Reasons Behind Hives on Skin?
In Traditional Chinese Medicine (TCM), hives are related to diet, genetics, or a body constitution imbalance.
Physician Lim Sock Ling explains, “People who inherit an intrinsic body type or weak Lungs are most vulnerable to skin allergies. Unhealthy eating will accumulate Heat and Dampness in the stomach and intestines, contributing to an outbreak of hives. Blood Deficiency can lead to skin itchiness and dryness.”
Some of the more common types of hives include:
This type of hives is uncommon and can develop after exposure to cold water, temperature, or objects. It’s unclear what causes the condition.
However, it has been linked to infections and underlying health problems. In TCM, cold hives are believed to be brought on by Wind and Coldness.
Like cold hives, solar urticaria is also rare. A person diagnosed with this type of hives will briefly develop skin swelling after exposure to natural sunlight.
The emission of light from an artificial source can also provoke the onset of the condition.
Actions that vibrate skin are the main culprit behind this type of hives. Examples of these are:
- Mowing a lawn
- Riding a horse
- Cycling over a stone pathway
- Massaging or towelling an area of the body
- Using power tools like drills, jackhammers, and metal grinders
The rapid development of a skin rash is the most notable trait of aquagenic urticaria. Sometimes, a person may also suffer itching.
Aquagenic urticaria happens when a person’s skin encounters water, irrespective of temperature.
A common type of hives, cholinergic hives stem from sweat-inducing stimuli and prompt a temporary onset of itchy skin bumps. TCM associates the Wind-Heat pathogen with the occurrence of these hives.
Downward pressure or trauma will lead to the appearance of swollen skin in people with dermographism. It’ll take the shape of the applied external force. A person with this type of hives can also experience symptoms like itching and skin redness.
Pressure or delayed pressure hives
Dermographism and pressure hives share a common characteristic; the appearance of skin bumps after applying force. However, pressure hives can also cause pain, itching, and a burning sensation on the skin. Pressure on the skin from tight-fitting clothing or a purse strap for example, can apply enough pressure to cause hives.
The symptoms of this type of hives can develop immediately after stimulation or after four to six hours. Pressure hives can also be aggravated by heat, aspirin use, or menstruation.
How Hives are Diagnosed
A healthcare provider can usually diagnose hives by looking at the rash. They may also conduct a blood test and a skin prick or patch test. A small amount of the allergen is applied on skin to see if it reacts to determine the underlying triggers of the condition.
Remedies for Hives on Your Skin
Making a few simple changes to your lifestyle can help relieve itching in people with chronic hives. These include:
- Avoiding environments with high temperature or humidity
- Wearing loose-fitting clothes and clothes made from cotton fabric
- Using a fragrance-free skin moisturiser several times daily to prevent dry skin
- Applying a cold compress to an affected area of skin (unless you’ve been diagnosed with cold hives, of course)
Over-the-counter or prescription antihistamines are suitable for treating hives. The medication’s mode of action is to suppress the effect of histamine. Histamine is a type of chemical in the skin that causes allergy symptoms.
It’s preferable to use antihistamines that don’t make a person woozy. These are more effective, induce fewer side effects and you can take them more than once daily. An allergist may suggest combining two or three types of antihistamines with cold compresses or anti-itch to ease a person’s symptoms.
Studies show that acupuncture can successfully calm the symptoms of hives. This is attributed to the treatment’s ability to improve blood circulation, thus reducing inflammation. Several acupuncture points commonly used to treat hives include:
- Qu chi (LI11, 曲池)
- Xue hai (SP10, 血海)
- San yin jiao (SP6, 三阴交)
- Zu san li (ST36, 足三里)
Herbal formulas and ingredients
A person may use herbal formulas and ingredients to tackle the specific internal imbalances that cause hives. Physician Lim recommends these common formulas:
