Hi and welcome to Healthcaremagic. Thank you for your query. I am Dr. Rommstein, I understand your concerns and I will try to help you as much as I can. Most causes of dicharge and pain in breast are benign and not serious. It is usually minor nipple infection. There are a number of causes that may primarily be related to changes in hormone levels. These can include:Menstruation and premenstrual syndrome (PMS), Mastitis, Menopause and Fibrocystic Breast Tissue which is most common. Fibrocystic breasts are not necessarily linked to cancer, and the lumps are fluid filled cysts rather than a mass of cells. However, it is advisable to do breast ultrasound and mammography just to be sure and start regular follow up of possible cysts. In case of redness, fever and progressive pain this may indicate abscess and then it should be surgically drained or evacuated by needle under control of ultrasound. I hope I have answered you query. If you have any further questions you can contact us in every time. Kindly regards. Wish you a good health.
