Hi. I Am A 38 Year Old Female. I'm Going

Hi. I am a 38 year old female. I'm going to get straight to the point. The areolas of my breast have been sore and for the past 2 days. I know it can't be pregnancy because my tubes have been ties, clipped, and burnt. My last period was 2 and a half weeks ago. Could you please tell me what this could be? Thanks in advance.
