Hi, welcome to the ehealth forum and I am glad to help you.
Your concern seems to be painful itchy red bumps with some drainage which started on your daughter's ankles and then spread to shins, thighs, hands and elbows.
The possibilities in your daughter's case include boils, insect bite , contact with an irritant such as poison ivy or hives. The boils require an antibiotic whereas others are usually helped by steroid cream and cool compresses to control the itching. You must consult your personal physician for definitive diagnosis as the same is not possible online.
Hope this helps. Take care.
Note: This post is not to emphasise final diagnosis as the same cannot be made online and is aimed just to provide medical information and no treatment suggested above be taken without face to face consultation with health care professional.
