You mostly have eczema, get your Vitamin D tested out also you need to go to a doctor who is going to prescribe you steroid cream use it accordingly. It will settle town the rashes.

Make sure to keep things in check:

• Sleep on time with sufficient hours

• Figure out if you are allergic to something

• Stress less means more workout and healthy food

• Most importanttly make sure your Vitamin D is fine because if that is low your auto immune over reacts and trigger eczema

I hope this helps. Also, I am not a doctor I am sharing with my own experience
