Hello,
From the symptoms it looks like hives or allergies or contact dermatitis. Avoid using any lotions and creams for the meantime. Wash the skin with a mild cleanser with moisturizing properties like Cetaphil. Pat it dry. Then apply a good hypoallergenic moisturizer over the area and see if this improves.If the symptoms still persist then you can apply mild steroid like dermacort. For the itching
take some antihistaminics like Benadryl or Claritin.
If the irritation persists then please get it evaluated from a dermatologist.
I hope it helps. Take care and please do keep me posted in case you have any additional doubts. Kind regards.
