Why does sweating cause an itchy red rash? (photo)

My daughter has been getting these itchy spots lately when she perspires. She does not have any history of eczema. The doctors whom we went to only prescribed creams and anti-itch tablets, which does not help the condition. 

Thank you for your question. There are various causes of itchy bumpy rashes and these include eczema, bite reaction and scabies.

Heat and sweat can aggravate eczema and make the skin more itchy. Excessive scratching can also make the rash worse.

However, if the rashes are still persistent, it will be good to see your doctor or dermatologist again to re-evaluate the rash to endure a proper diagnosis and treatment.
