Hi, I can understand your concern for horrible red raised flaky itchy rash that started on lower legs and spread to arms and around eyes. There can be multiple possibilities of your concern but I can make a possibility of Allergic dermatitis or urticaria. In Allergic dermatitis there are eruptions along with moderate itching and in more aggravated cases there is appearance of more redness which persits for more than mutiple of days. In this condition a thorough history of contact allergens are to be taken and accordingly a specific diagnostic technique known as patch test is to be undertaken. In urticaria- there is presence of mutiple red patches for few hours and then subsides. YOU can wait for the Antinuclear antibody test report and then can meet a dermatologist for best help. The only precaution you must follow is not to touch, pinch pop or squeeze any of them other wise it can get infected and can cause complications. You can apply medium potency steroid cream application such as mometasone or fluticasone cream. You can take antihistamine benadryl or loratadine by mouth. Take care.
