Hello,
Without examination it is very difficult to confirm a diagnosis, but the symptoms are suggestive of prickly
heat(malaria) or sweat dermatitis. Prickly
heat (
miliaria) is an itchy skin rash 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.
