Allergy in the Skin
A red, itchy rash and pimple-like lesions on the Skin may correspond to an allergy known as eczema.
It is usually related to a particular food or environmental element that does not cause a problem for another person but to which the allergic person overreacts.
Treatment includes avoiding those that cause allergies, creams with antihistamines or corticosteroids, and, sometimes, these types of drugs by mouth.
If you usually have these types of problems, it is convenient to prevent their appearance:
- I am keeping the Skin hydrated with natural or hypoallergenic emulsions.
- I am avoiding processed, dairy, and excess meat.
Rash on arms from the sun
If your arms were bare when you were overly exposed to the sun, that might cause a skin rash.
This can also happen with minimal exposure in some instances:
- Very white, sensitive, or allergic Skin.
- Intake some antibiotics or drugs that cause sensitivity to the sun: some antibiotics, anti-inflammatories, antihypertensives, and diuretics.
In these cases, you may feel burning, pain, or notice redness, itching, and warmth.
You can improve that Rash by applying cool, wet compresses, but notice because you can burn yourself.
It may also help to use a fluid cream. It is advisable to apply aloe vera since it will not only refresh the area but also reduce inflammation and discomfort.
Skin rash from inflammatory skin diseases
Some inflammatory diseases can cause reddened lesions, peeling, itching, or burning of the skin of the arms, such as psoriasis or lichen planus.
The lesions can also be in other areas of the Skin and can even affect the nails, the scalp, or mucous membranes.
Your doctor may order lotions, creams, or medications by mouth to control the symptoms to treat these diseases.
Improving your eating habits can bring you great benefits.
At all costs, you should avoid scratching, as it makes injuries worse. In cases of significant discomfort, you can apply compresses moistened with fresh water or with natural infusions of veronica, thyme, or bellflower.
Infections that can present as a rash
Among the infections that can manifest with a rash, we find:
Viral infections
Some viruses can give rise to red, itchy lesions, such as chickenpox or measles. In the case of chickenpox, when the vesicles rupture, they release a clear liquid and form scabs.
Respiratory symptoms and discomfort with fever usually appear in the first days, even before the Rash appears.
The Rash usually gets better on its own after a few days. Only the symptoms should be treated, menthol powder can be applied if it stings a lot, or an antihistamine can even be administered.
Aspirin should not be used to lower fever.
Bacterial infections
Suppose the area where the Rash has previously suffered a skin lesion or has been scratched too much; the cause of the redness, pain, and swelling maybe bacteria. This is usually worse in people with low defenses, such as those with diabetes.
Local or oral antibiotics are usually necessary.
Parasitic infections
Such is the case of scabies, better known as scabies. In this case, the mites usually choose the areas between the fingers, wrists, and forearms to locate themselves. The lesions tend to itch excessively at night. There may be lesions in other body areas, such as the genital.
There are special creams and lotions with permethrin to treat scabies. You also need to wash clothes and bedding in hot water every day. The whole family should do the treatment.
Fungal infections
Above all, it can be seen when the Skin is macerated by constant moisture. The Skin may be red, burning, or itchy, and white patches may be seen.
Treatment consists of avoiding humidity and using antifungal creams.
Contact dermatitis
A rash on the arms can be caused by direct contact of the Skin of the forearms with some substance. It may be due to:
- Permanent moisture
- Irritating substances, such as cleaning products or cosmetics.
- Substances such as latex only affect allergy sufferers.
Lesions of this type tend to itch or burn; the Skin is red and may peel or be drier than usual.
To improve this problem, you need to:
- Stop having contact with the irritant substance.
- Avoid constant humidity.
- Moisturize the skin with natural, chemical-free, or hypoallergenic creams.
- Wear cotton gloves under latex or plastic gloves and change them when they get wet.
Hives on the Skin from insect bites
Mosquitoes, spiders, and fleas are usually the insects that most frequently can cause rashes with pimples or hives that are pretty itchy.
To improve that itching, you can apply cold compresses, and you should avoid scratching so that the Skin does not become superinfected.
