Dear sandra137: There could be many possible explanations for burning pain in the nipple, including trauma (from sucking). If this does not resolve or becomes worse, you should have your doctor check it out.
In addition to this I have benign bellateral lumpy breast and I went to see a breast surgeon 2 yrs ago. She evaluate it and said its normal to have lumpy breast. Pls help me anyr esponse will be really appreciated!
