Hello doc. There is this spotting of blood from my left nipple die to some crack i guess or i have got my nipple injured die to something ...first i saw it 3-4 days back and i guess it was healing also as no blood was spotted later....then i slept on my tummy last night and after that i think from pressing the bleeding is again happening and i can spot stains. Although there is no pain. But then also i wanted to consult a doctor was this. Please guide.
