Hello,
Without examination, confirmation of a diagnosis is tough, but it can be an allergic reaction,dermatitis,hives,eczema or heat rashes.

Avoid using any lotions and creams for the meantime.Use a mild cleanser with moisturizing properties like Cetaphil. Also use cotton clothes and change the clothes twice if there is any increased sweating. Try keeping the skin free of sweat as far as possible. If the symptoms still persist then you can apply mild steroid like dermacort.As there is itching,so pls take antihistaminics like Benadryl or Claritin.

If the symptoms persist then consultation of a dermatologist will be the best.
I hope that helps.Take care and pls do keep me posted on how you are doing or if you have any additional doubts.Kind regards.
