Sharp pain in right breast

Hi for the last few months I've been experiencing a sharp almost stabbing pain the runs from my nipple to my rib cage (straight down) I guess, it was particularly bad today, almost all Day it's been hurting. I've put it down to nerve regeneration in the past but now I'm not so sure, I'm 12 month post op on the 14th of next month, surely this isn't normal so far post op? im going to ring my ps on Monday but thought I would get opinions on what it might be here in the mean time. They look and feel normal to touch
