Hi, The possible causes of your galactorrhea are: -If you are not using any contraceptives and if you had unprotected intercourse around the time of ovulation, the possibility of pregnancy cannot be excluded. In that case, please go for a urine pregnancy test once. -Breast tenderness can be seen in premenstrual period, which will usually subside after onset of periods. Now, as you are having tenderness and galactorrhea, elevated serum prolactin levels or injury and /or friction to the nipples has to be ruled out. So, please consult your Gynecologist once, get examined and go for serum prolactin level estimation. If she suggests you may need to go for sonomammaogram also. With this workup the possible cause of your problem can be identified and treatment can be planned accordingly. Meanwhile cold compresses to the breast can relieve the pain to some extent. Take care. Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. Sree Gouri S. R., OBGYN
