I pumped for almost 9 months. i stopped pumping 7 months ago. one of my nipples went back to normal but the other one remained large as it was during pregnancy and pumping. some nipple pores on it are long, too?

Watch and wait: If you do not have an abnormal discharge, you may leave it alone, Some asymmetry in organs is normal. One breast, usually left, is often larger than right one. Have a healthy diet, exercise 30 minutes/day, drink plenty of water daily so your urine is mostly colorless, have safe sex, no tobacco alcohol weed or street drugs.
