Rubella: Small Red Spots All Over The Skin
Another viral skin rash that affects children and young adults is rubella, or German measles. Rubella causes a rash of red skin spots that spreads like chickenpox from the face down. The skin rash can be itchy. Other symptoms include sore throat, fever, swollen glands, headache, and runny nose. There is a vaccine for rubella, and the Centers for Disease Control note that the virus has been eliminated from the United States, but it is still common in other countries. Rubella can be very dangerous for pregnant women because it can cause birth defects. Treatment includes rest and acetaminophen to relieve discomfort.
What Can Urticaria Look Like
The inducible type of hives is triggered by a physical stimulus and can be either acute or chronic. Physical causes can result in repeated episodes of acute hives, or a persisting long-term condition.
Hives can be classed as follows:
- Acute – if it develops suddenly and lasts less than six weeks. Most cases last 24-48 hours. In some cases the rash only lasts a few hours. About 1 in 6 people will have at least one bout of hives in their lives. It can affect anyone at any age. Some people have recurring bouts of acute hives.
- Chronic – if it persists longer than six weeks. This is uncommon.
Hives can be triggered by a number of different physical causes. The reason why a rash appears in affected people is not clear. The physical stimulus somehow causes a release of histamine and other chemicals, which causes the rash.
The main types of inducible urticaria include the following:

What Causes Dermatitis Herpetiformis
Despite its name, the herpes virus does not cause DH.
DH is caused by a sensitivity or intolerance to gluten. Gluten is a protein found in wheat and grains. When you have DH and eat food with gluten, the gluten combines with an antibody from the intestines. As the gluten and antibody circulate in the blood, they clog small blood vessels in the skin. This is what causes the rash.

- Measles is a viral respiratory infection that causes a widespread rash consisting of itchy, red bumps.
- Scarlet fever is an infection due to group A Streptococcus bacteria that produces a toxin, causing a bright red or skin-tone-colored, sandpaper-like rash.
- Hand, foot, and mouth disease is a viral infection that can cause red lesions on the mouth and a rash on the hands and feet.
- Fifth disease is a viral infection that causes a red, flat rash on the torso, arms, and legs.
- Kawasaki disease is a rare but serious illness that triggers a rash and fever in the early stages and can lead to heart complications.
- Impetigo is a contagious bacterial infection that causes an itchy, crusty rash and yellow, fluid-filled sores on the affected area, such as the face, neck, or hands.

When Should I See My Doctor
See your doctor if you are very itchy and there is no rash. It is very important to let them know about the medications/supplements, drugs or herbal medicines you may have taken.
- the lips or tongue are swollen
- you or your child have trouble breathing
- you are unwell or have a fever
- the symptoms keep coming back
- the itching is so bad you cannot sleep
- the rash is bleeding, scabs or has pus
- you develop severe itching while you are pregnant
It is always a good idea to see a doctor if your baby develops a rash.
When Hives Wont Go Away
If you are unlucky enough to still have hives after six weeks, its likely to persist six months, six years or even 26 years later.
This is what dermatologists call chronic urticaria, which affects about 1% of the population . The itch, sleep disturbance, swelling and rash associated with it severely impair peoples quality of life. Of all skin diseases, chronic urticaria seems to worsen your mood and disrupt day-to-day living the most.
One antihistamine tablet is usually enough to control hay fever. But people with chronic urticaria may need two, three or sometimes four tablets a day to control their itch. Even that may not be enough to stop the wheals.

Home Remedies To Treat Itchy Red Bumps On Your Skin
Some itchy red bumps stay for a short time some others tend to stay for longer periods. In fact, some skin infections can last a lifetime.
While most rashes can be treated with over-the-counter products like antihistamines and hydrocortisone creams, simple home remedies can relieve symptoms and clear up the unsightly rashes in no time.
When you get a nasty skin rash, here are some remedies you can try out.
- Apply a cold compress on the region of the infection will help reduce the swelling and the urge to itch.
- Using a good moisturizer will prevent your skin from breaking. Apply your moisturizer twice a day immediately after you take your bath.
- Apply hydrocortisone, calamine lotion, or any other anti-itch cream to reduce the urge to itch. Most topical creams are readily available in drug stores or pharmacies.
- If you have sensitive skin, using harsh soaps and detergents could worsen the itchy skin. Instead, use skin-sensitive soaps or unscented detergents.
- Avoid scratching. The itch can be intolerable most times. However, scratching your rash can damage your skin or spread it from one area of your body to another. When you feel itchy, you can distract yourself by exercising or playing a game.
- If your body reacts to extreme temperatures, you can take a lukewarm bath to avoid triggering a rash.
- Avoid substances that irritate your skin.
Itchy Bumps On The Skin In Children
There are several common causes for itchy, red bumps or patches on one or more skin areas. The conditions covered here are mostly limited to just a few bumps or to small areas of the body. Some of these disorders, however, may also involve large body areas, but these are discussed specifically under the Itchy Rash section.
The location on the body of the bumps often provides a clue to their cause. Genital bumps may indicate molluscum or scabies, while an itchy scalp may be caused by head lice, a fungus , or a form of eczema called lichen simplex. A form of eczema on the hand and scabies affect the hands or feet, while an inherited condition, keratosis pilaris, usually affects the upper arms. Insect bites are typically found only in exposed areas that are not covered by clothing or hair. Sometimes, the type of insect may be deduced by the body location and pattern of bites. Flying insects bite any exposed area, and the bites are often sporadic, while flea bites tend to be on the legs in groups of 3 or more nearby bumps. Impetigo is common on the face but may occur anywhere, as may the viral infection called molluscum.
What Are The Symptoms
An itchy rash is the main symptom of hives . The rash can affect any area of skin. Small raised areas called weals develop on the skin. The weals look like mild blisters and are itchy. Each weal is white or red and is usually surrounded by a small red area of skin which is called a flare. The weals are commonly 1-2 cm across but can vary in size. There may be just a few but sometimes many develop over various parts of the body. Sometimes weals that are next to each other join together to form larger ones. The weals can be any shape but are often round.
As a weal fades, the surrounding flare remains for a while. This makes the affected area of skin look blotchy and red. The blotches then fade gradually and the skin returns to normal. Each weal usually lasts less than 24 hours. However, as some fade away, others may appear. It can then seem as if the rash is moving around the body. The rash may clear completely only to return a few hours or days later.
Impetigo: A Skin Rash Caused By Bacteria
Impetigo is a rash caused by a skin infection, usually traced to one of two bacteria, group A streptococcus or Staphylococcus aureus. This skin rash appears as brown, crusty sores or blisters around the nose or mouth area. The rash is very itchy and very contagious. Scratching the rash and then touching other areas of the body, or other people, will cause it to spread. Treatment of impetigo is with antibiotic creams or lotions, and for more severe cases, with oral antibiotics.

Treatment for allergic eczema depends on the severity of your symptoms. In all cases, though, its important to wash the affected skin with plenty of water to remove traces of the allergen.
You may not need additional treatment if your symptoms are mild and dont bother you. However, you might want to use a moisturizing cream to keep the skin hydrated and repair damage. Over-the-counter corticosteroid creams can help with itching and inflammation.
Your doctor may recommend prescription-strength ointments or creams if your symptoms are severe. They may also prescribe corticosteroid pills if needed.
Complications Of Itchy Skin
It’s quite common to find that after you have scratched an itch that it becomes more persistent and you get into a cycle of itching and scratching. This can be painful and can sometimes lead to an infection if the skin is broken.
The scratching can also lead to brown or pale marks on the skin, lumps, bruising or scarring.

DH may be well-controlled with treatment. Specific treatment will be determined by your healthcare provider based on:
Your age, overall health, and medical history
Extent of the condition
Your tolerance for specific medicines, procedures, and therapies
Expectation for the course of the condition
Your opinion or preference
The symptoms of DH may go away if you cut all gluten from your diet. Healing may take several weeks to months. Your healthcare provider may also prescribe a medicine called dapsone.

If dapsone is prescribed for you, your healthcare provider will carefully monitor your blood count.

If you are prone to hives or swelling, talk to your healthcare provider about getting an allergy test. Once you know what triggers your allergies, you can take steps to avoid your triggers.
