What are the symptoms of prickly heat?
The main symptom of prickly heat is a red and slightly swollen rash consisting of tiny red spots or blisters. As the name suggests, the rash often feels itchy or prickly. Adults usually develop the rash in areas where sweat collects, such as the back, armpits, inner thighs, under the breasts and in the elbow and knee creases. In babies, the rash is most common on the chest, shoulders and neck, but can also appear in the armpits, groin and elbow creases.
