Nursing is the best way to get rid of one. Frequent nursing is crucial to completely empty the breast, for comfort and to reduce inflammation.
You can also massage the area frequently and firmly, starting at the top of the breast and working your way toward the nipple. Applying warm compresses before nursing can help empty the breast.
Also you can try to vary your nursing position. For example, if you use the cradle hold, try the football hold or nurse lying down. Also,you can position the baby at your breast with her chin pointed toward the clogged spot. This directs suction at the plugged duct and seems to promote healing.
Some women also report success using herbal remedies such as echinacea, lecithin, and vitamin C. Taking ibuprofen may help relieve pain and inflammation,if it starts, but ask your doctor first.
You also should try to avoid going long stretched between feedings, or pumping. This will make things flow more freely.
