Hi, I noticed that a week before my period, there was a very small drop of blood coming from my right breast. Last Dec 2011, I experienced the same and saw my OB. She examined it and said it was just a crack due to dryness or something rough rubbed it. She asked me to treat it with petroleum jelly. It healed actually. But everytime i am about to have my period, I experienced a little tingling sensation on my right nipple then a week before my last period, I noticed a very small drop of blood from the said nipple. I can also feel something from my right breast, my OB said it is just a lymph node but I noticed it is larger that my left. Is it normal? I am 42 and somebody said that it might be hormonal. What other test do I have to take? I already undergo Mammo and Ultrasound, and I was advised of FNAB or repeat the test after 6 months. What would be the best thing to do?
