Breasts :: Discharge And Itching With Family History Of Cancer

I'm 34 years old. Family history of breast cancer.

My first benign breast (right) tumor was surgically removed when I was 15 years old. It was a mass that grew in size with time but, thankfully, benign.

In 2013 I had a lump in my left breast (mammo and ultrasound showed lump w/ it's own blood supply and jagged edges) and when I was having my biopsy done the Dr. saw there was puss. Biopsy returned normal and diagnosis was mastitis even though I wasn't breast feeding. After weeks and weeks of strong antibiotics, the mass was surgically removed.

In 2014 I had another lump in my right breast(mammo and ultrasound showed lump w/ it's own blood supply and jagged edges). During the biopsy my Dr. was able to break the mass apart. No surgery was needed after this one. No antibiotics. And again, biopsy was normal.

Now it's 2015 and about 2 weeks ago I woke up with pain on my right breast. It was very swollen, red around the areola, felt very dense/heavy, and was very warm. A few days later, symptoms are the same but now I had green discharge coming out of the nipple. I didn't squeeze to get the discharge out. I noticed it on my bra. Some days there was more discharge than other days, but always green. I think I might have seen a reddish brown color at one point but wasn't too sure as it was faded into the padding I was putting in my bra. Went to the Dr. and was seen by a nurse practitioner and she felt a lump (though to me, it didn't feel like a lump, more of just a very dense/thick area) and we noticed that my nipple was inverted and it wasn't before. I was finally scheduled for a mammo & ultrasound a week and half after the symptoms first started and by then, the swelling had gone down, the pain wasn't constant - more of a shooting sharp pain throughout my breast and nipple area, but the discharge continued. The nipple is still slightly inverted, specially at the bottom. Mammo and ultrasound came back fine except Dr noticed that there is debris in my milk ducts. Oh and no fever at any time, no feeling sick, and my breast is very itchy... nipple area is flaky... maybe from scratching?? Should I get a 2nd opinion or does this sound like something I should concerned about? I've had so many issues with my breast already I just get really scared that there is something bad going on. I'm sure this is benign but worried at the same time.
