Rashes


 

Rashes can be itchy and very irritating. Although most rashes are not life-threatening, some rashes can signal something more serious. If you have a rash and notice any of the following symptoms, see a board-certified dermatologist or go to the emergency room immediately:

  1. The rash is all over your body: A rash that covers the body could indicate something concerning, such as an infection or allergic reaction.
  2. You have a fever with the rash: If this is the case, go to the emergency room. This could be caused by an allergic reaction or an infection. Examples of rashes caused by infection include scarlet fever, measles, mononucleosis, and shingles.
  3. The rash is sudden and spreads rapidly: This could be the result of an allergy. Allergies to medications are common, and some can be serious. If breathing becomes difficult, go to the emergency room or call 911.
  4. The rash begins to blister: If your rash is made up of blisters, or if the rash turns into open sores, it could be the result of an allergic reaction, a reaction to medication, or an internal cause. Seek medical attention if a blistering rash affects the skin around your eyes, multiple areas in your mouth or your genitals.
  5. The rash is painful: Painful rashes should quickly be evaluated by a physician.
  6. The rash is infected: If you have an itchy rash and you scratch it, it may become infected. Signs of an infected rash are yellow or green fluid, swelling, crusting, pain and warmth in the area of the rash, or a red streak coming from the rash.

Rashes can come in many forms and, depending on the cause, take days or even weeks to heal. Rather than treating the rash on your own, see a board-certified dermatologist for the proper diagnosis and treatment.
