So to update here for all of us.
So far the antibiotics haven't made any changes and the areas are not growing but also not going away.
At this point, I'm wondering if it isn't a fungal infection. I have those under my breast but this doesn't look like it or feel like it. Nevertheless, I put some OTC Antifungal cream on it today...

I'm scared y'all. I guess I can take solace in that my mammogram was all clear. Nevertheless...I'm scared. Not gonna lie. Really scared.

Sigh...
