A skin rash is an abnormal change in the skin which affects its color, appearance and texture. It may affect one part of the body or even affect all the skin. Rashes cause the skin to itch, swell, be painful and become dry, cracked, and bumpy.
This condition is normally caused by skin inflammation resulting from a variety of causes. There are many types of skin rashes which include eczema, lichen planus, pityriasis rosea, and granuloma annulare.
Eczema is a common skin condition characterized by an inflamed, scaly, itchy and red skin. The condition is non-contagious and occurs in both adults and children. Its causes are not known, however, it tends to affect people with a family history of allergies.
Granuloma annulare is a chronic skin condition usually characterized by a circular-shaped rash with reddish bumps. This condition affects young adults and children mostly common in girls. Its cause is still unknown.
Lichen planus is another common skin condition which produces flat-topped bumps that are shiny on the skin with an angular shape and reddish-purple color. Though it can occur anywhere on the skin, it is mostly found on the insides of the ankles and wrists, the back, neck and lower legs. In rare cases, it may appear inside the mouth, nails, hair, and genital region. Though in most cases its cause is not known, it is often linked to Hepatitis C infection.
Pityriasis rosea is another common mild skin rash that begins with large and scaly, pink patches on the chest or back. The number and size of the spots usually vary accompanied with itching and redness. It is usually caused by a virus since the rash has a resemblance to certain viral illness.
What are the symptoms of skin rash?
Rashes last for about 5 to 20 days and their presence may aid diagnosis. Some of the most common signs and symptoms of rashes include:
-Brittle or split nails
-Dry and scaly skin that might become thick and leathery when scratched
-Rings of small, firm bumps over the backs of the forearms, feet, and hands
-Infection of the areas where skin is broken
-Formation of small fluid-filled blisters that ooze when scratched
How is skin rash diagnosed?
Diagnosis of skin rashes should take into account things like the appearance of the rashes, occupation, occurrence in other family members, what they have been exposed to, and other symptoms. A doctor might test a scaly or crusted area of the skin so as to rule out other infections and skin diseases. In most cases, the doctor diagnoses by looking at the skin but in some cases, a small bit may be taken from the affected area and sent to the lab for testing.
How is skin rash treated?
Atopic eczema can be treated with medications such as creams and ointments that help control swelling, itching, and redness of the skin. Treatment for granuloma annulare is often unnecessary unless for cosmetic reasons. Lichen planus cannot be cured; however, its symptoms can be treated using products that prevent itching. Mild cases of pityriasis rosea and even more severe cases can often go away without any treatment. However, exposure to sunlight may speed up the healing of sores.
