The degree of soreness, and where and how it is felt, differs for each woman. It might be sharp, stabbing, dull, throbbing or aching. It might be felt in all
or part of the breasts, one breast or both. It can also affect the armpit area.
For many women, the soreness is barely noticeable. For others, the pain is so great that it affects their everyday lives. Usually the condition goes away in time.
The medical name for breast soreness is mastalgia.
There are many reasons for breast soreness.
Most important is see your Doctor if you are worried :-)
