Hi,
How are you? What other symptoms are present and what specific part of the skin or body are they located? The red spots could be due to a variety of issues such as infection, irritation, hypersensitivity reaction or skin conditions such as dermatitis or eczema. If there is itchiness, try to avoid scratching your skin to prevent secondary bacterial infection. It is best that you check with your doctor for proper evaluation. Direct clinical examination of the spots is important. Take care and do keep us posted.
try Hydrocortisone cream bought OTC... it sounds like an allergy rash, what is it like is it raised red spots on a whitish background? Hives .Have you been using sun cream or putting on cream to protect you from the sun ?
