10/31 Right breast tender, color change to pink especially above & under the nipple. Warm to touch. 11/3 mammogram & ultrasound done. Nothing found. No reason for the tenderness or redness. No antibiotic given. 11/6 Not as pink or warm today but some sharp pain lasting about 2-3 minutes late this afternoon. Should I be concerned at this point or just wait a few days to see if it heals itself???
