What do you suggest if i have an itchy rash and want to know how i can get rid of it?

Allergy: Could be allergic or a contact like poison ivy. Don't scratch it that may lead to infection. Think if you put on anything , ate anything or contacted any allergen . Gardening? Steroid anti itch cream is a start if continues see a dermatologist

Suggest eval: These lesions need to be visualized & a history needs to be obtained in order to make an accurate diagnosis. Sometimes lab testing or biopsy is necessary.
