Dermatitis/Rash
Rash
Your skin is your largest organ, and it provides the first line of defense against threats that could cause serious damage to the underlying tissue. Your skin comes into contact with many irritants and substances, and these can cause a number of skin conditions. Environmental factors and stress can also exacerbate some skin conditions.
One of the most common skin conditions you may experience is a rash. A rash refers to a red, inflamed patch of skin that may or may not be itchy. When the rash is caused by contact with an irritant, it's called contact dermatitis. A mild case of dermatitis might present itself as simply a discoloration of the skin. A more severe reaction will be deeper red and inflamed, it may be accompanied by blisters.
Many substances can cause contact dermatitis, and you may not experience a reaction the first time you come into contact with these substances. Here are some of the more common irritants you may encounter:
-- Poisonous plants
-- Perfumes, soaps, deodorants and other scented substances
-- Jewelry, especially containing nickel
-- Latex
Rashes can also more rarely be caused by medication allergies, fevers and even emotional stress. Viral, fungal and bacterial infections can all be responsible for skin rashes; parasites and insect bites are also known to cause rashes and other skin reactions. Finally, some skin conditions like eczema and psoriasis can be accompanied by a rash.
Depending on the cause and severity of your rash, treatment options will vary. Many mild rashes resolve on their own once the irritant has been removed. Steroidal creams can help to reduce inflammation and manage symptoms. If the rash is caused by an infection, that infection will need to be treated with an antibiotic, anti-fungal or other type of medication to destroy the pathogens behind the infection.
Because rashes can have such diverse causes, it's important to follow up with a doctor for any rash that's long-lasting or severe. It's also important to obtain medical care for any rash that's accompanied by a fever, nausea, or shortness of breath. Additionally, if your rash peels or weeps fluid, you should see a doctor for immediate treatment.
