IDC /Burning Type of Sensation Anyone

I have IDC grade 3 newly diagnosed and have not had surgery yet. For a few months I have had this burning type of sensation/pain on the same side of the breast where my cancer is. I originally thought my bra was causing the discomfort. It is not all the time it just comes and goes from time to time. It only last a few seconds and stops. I just think it's odd.
