Geez....your physician sounds like she could really care less.
Ok, the mammogram was ok, however, I would recommend having this biopsied. In fact, I would recommend requesting a referral to a Dermatologist and getting this biopsy done by the Derm.
I am not exactly sure what you are dealing with. It looks like something Eczema-like and Paget's can present just like Eczema. The biopsy will determine exactly what this is.

Did the doctor even mention checking for inflammatory breast cancer? Apparently some docs are unaware of it, so you need to see a doc who knows about it. Call a breast specialist, perhaps.
