A rash is defined as a widespread eruption of skin lesions. It is a very broad medical term. Rashes can vary widely in appearance. Their causes range from insect bites to HIV and reactions to medications.
A rash can affect one part of the body or cover a large area. Rashes can also be dry, moist, bumpy, smooth, cracked, or blistered. They can involve pain, itching, and color changes.
Some rashes will clear up on their own, some respond to home remedies, but others might be a sign of something more serious that needs medical attention.
Rashes can happen for many reasons, including skin infections, allergies, and medications. They can also result from bacterial, fungal, viral, or parasitic infections and other diseases.
Allergies and sensitivities to food and other substances can cause skin rashes.
One of the most common causes of rashes — contact dermatitis — occurs when the skin has a reaction to something that it has touched. The skin may become inflamed, and the rash tends to be weepy and oozy.
Common causes include:
•dyes in clothes
•beauty products
•poisonous plants, such as poison ivy and sumac
Certain medications can cause rashes in some people, either as a side effect or an allergic reaction.
Some medications, including certain antibiotics, can also cause photophobia or photosensitivity. This means they make the individual more susceptible to sunlight. The photosensitivity reaction looks similar to a sunburn.
In an allergic reaction, a person’s immune system mistakenly attacks the medication as if it were a pathogen. Symptoms vary depending on the individual and the drug but can include:
•a rash, including hives
•itchy skin or eyes
•swelling
Infections that involve bacteria, viruses, fungi, or parasites can also cause a rash. These rashes will vary depending on the type of infection. For instance, candidiasis, a common fungal infection, causes an itchy rash that generally appears in skin folds.
Anyone who believes they may have an infection should seek medical advice.

•skin that appears black or dead
•irritation or burning in the affected area

•numbness and pain
Inhaling the fumes could lead to swelling of the throat, lips, and tongue and difficulty breathing.
Rashes come in many forms and develop for many reasons.
However, some basic measures can speed up recovery and ease some of the discomfort:
•Use mild soap, baby soap, or soap for sensitive skin. Avoid scented soaps.
•Wash in warm water, not hot water.
•Wear loose-fitting cotton clothes.
•Ask a doctor or pharmacist about using moisturizers and emollients.
If a rash occurs with the following features, a person should seek medical advice:
•a sore throat
•pain in joints
•a recent animal or insect bite
•red, purple, or dark streaks near the rash
•tender regions near the rash
How can I identify my rash?
A person may be able to identify the cause of their rash based on the location of the rash or other symptoms they may experience. For example, swelling and breathing problems might indicate an allergy, while a fungal infection such as candidiasis can cause a rash in the skin folds. Factors such as whether the rash is flat or raised, peeling, or painful can help determine the type of rash. However, it is best to contact a doctor for an accurate diagnosis if a person develops a rash.
