Heat Rash (cont.)
How is heat rash diagnosed?
The diagnosis of heat rash or prickly heat is made by physical examination. Knowing that the rash appears during sweating or heat, appreciating the location on the body (in skin creases or where clothes fit tightly) and seeing what the rash looks like is enough to make the diagnosis. As with many rashes, the health care professional may look at the involved skin and because of previous experience, immediately make the diagnosis.
