lLet me give you the exactly name of the procedure : Operation performed: ULTRASOUND GUIDED LEFT BREAST MASS BIOPSY WITH WIRE FOR LOCALIZATION
The procedure it was on 3/16 until now the botton of my nipple still swollen Why???
What you are talking about is inflammation.
After any operative procedure the area is swollen/inflammed.
It takes atleast 1 week to the pain to subside and for complete normal stature it will take 3-4 weeks time.
