Odd rash.

So ive had this rash on various parts of my body. It started where my appendix scar is in a little spot, got bigger and went away. But still faintly visable. This picture is on the inside of my leg on the upper part. Still hasent even faded it just added another spot, and now I have a tiny one on my stomach. Ive had eczema my entire life but this isnt it. Does anyone have any ideas ive tried all my eczema creams and nothing works =/ I really dont wanna go to the doctor over a rash.
