Rash on aereolas and in/around belly button

I have a red rash in my belly button and on both breast. It is localized to the aereolas only, it does not extend any further out onto the breasts. My breasts do not itch at all, my belly button does midly from time to time. Not even bad enough that I want to scartch it. I had the same rash this winter, but just on the aereolas at that time, not the belly button. No discharge at all. I have had the rash now for a month and a half. When I had it this winter, just on my aereolas, it lasted three weeks. I went to the Dr. for it this winter and they thought it was possibly a yeast infection and I was given a cream. It did not help, nor has it helped this time around. I have also tried hyrocortisone cream with no luck. Seems odd as it was and is now only on the aereolas and does not spread out any further. As far as my belly button goes, it is on the inside and only extends out about 1/2" from the opening. I initially thought allergic reation as I grew up with allergies but have not changed any products or my diet. This is the weirdest and longest rash I have ever had. Any help would be GREATLY appreciated!! Thank you for your time.
