Hives are a common skin condition that can affect people of all ages. They are raised, red, itchy bumps that can appear anywhere on the body. Hives can be caused by a variety of factors, including allergies, infections, and stress.
In this article, we will take a closer look at hives, including what they look like, what causes them, and how they are treated. We will also provide tips for preventing hives and managing the symptoms.
Hives can vary in size and shape, but they typically appear as raised, red, itchy bumps. They can be as small as a pinhead or as large as a dinner plate. Hives can also be singular or appear in clusters.
What Do Hives Look Like?
Hives are raised, red, itchy bumps on the skin that can vary in size and shape.
- Raised, red bumps
- Itchy and uncomfortable
- Vary in size and shape
- Can appear anywhere
- Often caused by allergies
- Can also be caused by stress
- Usually go away within a few days
- Treatment includes antihistamines

If you are experiencing hives, it is important to see a doctor to determine the cause and receive appropriate treatment.
Raised, red bumps
One of the most common symptoms of hives is the appearance of raised, red bumps on the skin. These bumps can vary in size and shape, but they are typically round or oval and smaller than a dime. They can be red, pink, or skin-colored, and they often have a pale center.
Hives can appear anywhere on the body, but they are most commonly found on the arms, legs, trunk, and face. They can also appear on the palms of the hands and soles of the feet. Hives can be singular or appear in clusters, and they can range in number from a few to hundreds.
The raised, red bumps of hives are often accompanied by itching, which can be mild to severe. The itching can be so intense that it can interfere with sleep and daily activities. In some cases, hives can also cause swelling, pain, and a burning or stinging sensation.
Hives are usually a harmless condition that goes away within a few days or weeks. However, in some cases, hives can be a sign of a more serious underlying medical condition. If you are experiencing hives that are severe, persistent, or accompanied by other symptoms, such as fever, chills, or shortness of breath, it is important to see a doctor right away.
Hives can be triggered by a variety of factors, including allergies, infections, stress, and certain medications. In some cases, the cause of hives is unknown. If you are able to identify the trigger for your hives, you can take steps to avoid it and prevent future outbreaks.
Itchy and uncomfortable
One of the most common symptoms of hives is itching. The itching can be mild to severe, and it can be so intense that it can interfere with sleep and daily activities. In some cases, the itching can also lead to skin damage if the person scratches excessively.
The itching associated with hives is caused by the release of histamine and other inflammatory mediators from the mast cells in the skin. These mediators cause the blood vessels to dilate and the surrounding tissue to swell, which leads to the raised, red bumps characteristic of hives. The itching is a response to the inflammation and irritation caused by these mediators.
There are a number of things that can make the itching worse, including heat, sweat, and tight clothing. Scratching the hives can also make the itching worse, as it can further irritate the skin and release more histamine.
There are a number of things that can be done to relieve the itching of hives, including:
- Taking a cool bath or shower
- Applying a cold compress to the affected area
- Using an anti-itch cream or lotion
- Wearing loose, comfortable clothing
- Avoiding scratching the hives
If the itching is severe, your doctor may prescribe oral antihistamines or other medications to help relieve the symptoms.
Vary in size and shape
Hives can vary in size and shape, but they are typically round or oval and smaller than a dime. They can be as small as a pinhead or as large as a dinner plate. Hives can also appear in clusters or as individual bumps.
- Size: Hives can range in size from a small dot to a large patch that covers a significant area of skin. The size of the hives can vary from person to person and from outbreak to outbreak.
- Shape: Hives are typically round or oval, but they can also be irregular in shape. Some hives may have a pale center with a red or pink border, while others may be uniformly red or pink.
- Clusters: Hives can appear as individual bumps or in clusters. Clusters of hives can range in size from a few bumps to dozens or even hundreds of bumps. Clusters of hives are often more itchy and uncomfortable than individual hives.
- Changing appearance: Hives can change in size and shape over time. They may start out small and then grow larger, or they may start out as individual bumps and then merge together to form clusters. The appearance of hives can also change depending on the severity of the outbreak and the individual's response to treatment.
The size and shape of hives can vary depending on the underlying cause. For example, hives caused by an allergic reaction are often smaller and more uniform in shape than hives caused by stress or infection.
Can appear anywhere
Hives can appear anywhere on the body, but they are most commonly found on the arms, legs, trunk, and face. They can also appear on the palms of the hands and soles of the feet. In some cases, hives may even appear on the inside of the mouth or throat.
The location of hives can vary depending on the underlying cause. For example, hives caused by an allergic reaction to food are often found around the mouth and throat, while hives caused by stress or infection are more likely to appear on the arms, legs, and trunk.
Hives can also spread from one part of the body to another. For example, hives that start on the arms may eventually spread to the legs, trunk, and face. This is more likely to happen if the hives are caused by a systemic reaction, such as an allergic reaction to a food or medication.
In most cases, hives are not a serious condition and will go away within a few days or weeks. However, if you have hives that are severe, persistent, or accompanied by other symptoms, such as fever, chills, or shortness of breath, it is important to see a doctor right away.
There are a number of things that can be done to prevent hives, including avoiding triggers, managing stress, and taking antihistamines. If you are experiencing hives, there are a number of things that can be done to relieve the symptoms, including taking cool baths or showers, applying cold compresses, and using anti-itch creams or lotions.
Often caused by allergies
Allergies are one of the most common causes of hives. When a person with an allergy comes into contact with an allergen, their body produces antibodies called immunoglobulin E (IgE). These antibodies bind to mast cells, which are found in the skin and other tissues. When the allergen binds to the IgE antibodies on the mast cells, it causes the mast cells to release histamine and other inflammatory mediators. These mediators cause the blood vessels to dilate and the surrounding tissue to swell, which leads to the raised, red bumps characteristic of hives.
There are many different types of allergens that can cause hives, including:
- Food allergies, such as allergies to peanuts, shellfish, and milk
- Drug allergies, such as allergies to penicillin and aspirin
- Insect stings and bites
- Latex
- Pollen
- Pet dander
- Dust mites
- Mold
In some cases, hives can also be caused by non-allergic triggers, such as:
- Heat
- Cold
- Stress
- Exercise
- Hormonal changes
- Certain medical conditions, such as lupus and thyroid disease
If you have hives, it is important to see a doctor to determine the cause of your hives and to receive appropriate treatment. Your doctor may recommend avoiding the allergen or trigger that is causing your hives, taking antihistamines or other medications to relieve the symptoms, and making lifestyle changes to reduce your risk of future outbreaks.
Can also be caused by stress
Stress is one of the most common causes of non-allergic and non-infectious types of urticaria (hives).
- Environmental stressors: Stressful life events, such as job loss, divorce, or the death of a loved one, can all trigger urticaria.
- Physical stressors: Things like extreme heat or cold, vigorous exercise, or even taking a hot bath can cause urticaria.
- Psychological stressors: Anxiety, depression, and other mental health conditions can all be triggers for urticaria.
It's important to note that stress-induced urticaria is not the same as an allergic reaction. In an allergic reaction, the body produces antibodies that bind to allergens, causing the release of histamine and other inflammatory mediators. In stress-induced urticaria, the exact cause is not known, but it is thought to be related to the release of stress hormones, such as cortisol and epinephrine.
Usually go away within a few days
Hives are usually a short-lived condition. In most cases, hives will go away within a few days or weeks, even without treatment. However, some people may experience chronic hives, which can last for months or even years.
There are a number of factors that can affect how long hives last, including:
- The cause of the hives: Hives caused by an allergic reaction will typically go away within a few days once the allergen is removed. Hives caused by stress or infection may take longer to go away.
- The severity of the hives: Mild hives are more likely to go away quickly than severe hives.
- The individual's response to treatment: Some people may respond better to treatment than others.
There are a number of things that can be done to help hives go away faster, including:
- Avoiding the trigger: If you know what is causing your hives, avoiding the trigger is the best way to prevent future outbreaks.
- Taking antihistamines: Antihistamines can help to block the histamines that are released by mast cells, which can help to reduce the symptoms of hives.
- Applying cold compresses: Cold compresses can help to reduce itching and swelling.
- Taking cool baths or showers: Cool baths or showers can also help to reduce itching and swelling.
If you have hives that are severe, persistent, or accompanied by other symptoms, such as fever, chills, or shortness of breath, it is important to see a doctor right away.
Treatment includes antihistamines
Antihistamines are the most common treatment for hives. They work by blocking the histamines that are released by mast cells, which helps to reduce the symptoms of hives, such as itching, swelling, and redness.
There are two main types of antihistamines:
- Non-sedating antihistamines: These antihistamines do not cause drowsiness, so they can be taken during the day without impairing your ability to perform normal activities. Examples of non-sedating antihistamines include loratadine (Claritin), cetirizine (Zyrtec), and fexofenadine (Allegra).
- Sedating antihistamines: These antihistamines can cause drowsiness, so they are best taken at night. Examples of sedating antihistamines include diphenhydramine (Benadryl), chlorpheniramine (Chlor-Trimeton), and hydroxyzine (Vistaril).
The type of antihistamine that is best for you will depend on your individual symptoms and needs. Your doctor can help you choose the right antihistamine for you.
In addition to antihistamines, there are a number of other treatments that can be used to relieve the symptoms of hives, including:
- Cold compresses: Cold compresses can help to reduce itching and swelling.
- Cool baths or showers: Cool baths or showers can also help to reduce itching and swelling.
- Calamine lotion: Calamine lotion can help to soothe the skin and reduce itching.
- Oral corticosteroids: Oral corticosteroids, such as prednisone, can be used to treat severe hives that do not respond to other treatments.
If you have hives that are severe, persistent, or accompanied by other symptoms, such as fever, chills, or shortness of breath, it is important to see a doctor right away.
Prevention includes avoiding triggers
The best way to prevent hives is to avoid the triggers that cause them. If you know what is causing your hives, you can take steps to avoid coming into contact with the trigger. For example, if you are allergic to peanuts, you should avoid eating peanuts and foods that contain peanuts.
If you are not sure what is causing your hives, your doctor may recommend allergy testing to help identify your triggers. Once you know what your triggers are, you can take steps to avoid them and prevent future outbreaks of hives.
In addition to avoiding triggers, there are a number of other things that you can do to help prevent hives, including:
- Managing stress: Stress can be a trigger for hives, so it is important to find ways to manage stress in your life. This may include exercise, yoga, meditation, or spending time with loved ones.
- Avoiding extreme temperatures: Heat and cold can both be triggers for hives, so it is important to avoid extreme temperatures whenever possible. If you must go outside in extreme temperatures, be sure to wear protective clothing.
- Using mild soaps and detergents: Harsh soaps and detergents can irritate the skin and trigger hives. Be sure to use mild soaps and detergents that are designed for sensitive skin.
- Wearing loose-fitting clothing: Tight clothing can irritate the skin and make hives worse. Be sure to wear loose-fitting clothing made from natural fibers, such as cotton.
If you have hives that are severe, persistent, or accompanied by other symptoms, such as fever, chills, or shortness of breath, it is important to see a doctor right away.
Seek medical help if severe
