From these symptoms the possibility os prickly heat needs to be ruled out. Prickly heat (miliaria) is an itchy
caused by trapped sweat. It tends to occur on areas of the body where skin touches skin, such as under the breasts, on the inner thighs, and under the arms. Tiny red spots with itching
and pricking sensation are the characteristic appearance of this rash.
Avoid using any lotions and creams for the meantime.
