What are the symptoms of a skin rash?

How is a skin rash diagnosed?
Because so many things can cause a skin rash, diagnosis can be tricky. Your healthcare provider will examine the rash, assess your symptoms and take a medical history. You may undergo tests, such as: Biopsy: Your healthcare provider can take a small sample (biopsy) of your skin or other tissue to check for the presence of a virus or bacteria. Allergy test: Allergy tests, such as skin prick (scratch) tests and patch tests, identify allergens. Prick testing is helpful for the diagnosis of urticaria; patch testing is helpful for the diagnosis of allergic contact dermatitis. In these tests, your healthcare provider exposes your skin to small amounts of allergy-causing substances and observes for a reaction. You might be tested for just a few allergens or many at once. You have an allergy if the skin turns red, swells or develops a rash. Blood tests: Some skin diseases can be caused by antibodies circulating in your blood, which may be detectable by blood tests. Other rashes may be the manifestation of another systemic illness, and blood tests need to be done to check for involvement of other organ systems.
How is a skin rash managed or treated?
Treatment for skin rashes depends on the cause. It can take several weeks for the rash to go away. Skin rash treatments include: Allergy medications: Oral antihistamines, a type of allergy medication, reduce itching. Anti-inflammatory creams: Hydrocortisone creams like Cortizone® soothe inflammation and itching. Immunosuppressants: If the skin rash is from eczema or an immune system response, medicines can reduce the reaction. Calming it can minimize inflammation (irritation). Oatmeal baths: Soaking in a warm bath with colloidal oatmeal can relieve dry, itchy skin rashes. Look for colloidal oatmeal bath products, such as Aveeno®, at your local drugstore. Steroids: If symptoms persist, your healthcare provider may prescribe a topical steroid cream or an oral steroid like prednisone. Steroids ease inflammation and itchiness. Topical immunomodulators: These medications change (modulate) your body’s immune system response to allergens. Prescription medications include tacrolimus ointment (Protopic®) and pimecrolimus skin cream (Elidel®).
What are the complications of a skin rash?
They’re bothersome and unsightly, but skin rashes usually respond well to treatment. They rarely cause serious problems. Potential issues include: Anaphylaxis: A severe allergic reaction can cause a skin rash and a life-threatening condition called anaphylaxis. Extreme swelling (angioedema) from anaphylaxis can close air passages. People in anaphylaxis need an immediate epinephrine injection (EpiPen®) to counteract this allergic response. If you’ve ever felt your throat or mouth swelling when you get a rash, talk to your healthcare provider about whether you need to carry an EpiPen®. Infection: Scratching an itchy rash can break open the skin, allowing germs to get in. Scratching puts you at risk for developing a bacterial skin infection.

What is the prognosis (outlook) for people with a skin rash?
Depending on the cause, some skin rashes go away with treatment. Skin conditions like eczema and psoriasis cause chronic, recurring skin rashes that need ongoing care. Treatments can soothe pain, inflammation and itching.
