Skin Rashes

Skin rashes may be an acute (sudden or short lived) problem or they may be a chronic persistent symptom. A rash should be considered chronic when it is present for more than 1-2 weeks. In that case it should always be seen by the physician, although it is not urgent.

Acute rashes are a common feature of many viral illnesses and are often preceded or accompanied by other symptoms such as a fever, runny nose, cough, vomiting, and or diarrhea. They can take many different appearances, but are almost harmless and need no treatment. Often they could itch – this is best treated with an antihistamine such as Benadryl (which is sold without a prescription – see below for dosage chart).

Rashes more rarely may signal serious disease. Signs that a rash may be a more urgent problem requiring prompt attention include: bruising or black and blue marks (without known trauma), bright red spots (like tiny blood blisters under the skin), inflamed eyes or oral mucous membranes, swollen hands, feet, or glands in the groin and underarms, and extensive blistering or breaks in the skin surfaces.

You should call right way if you observe any of the above symptoms, or if you child develops any signs of dehydration, pain, difficulty breathing, ect. If your child is showing any signs of respiratory distress call 911 immediately.
