This morning I woke up with my left breast feeling more tender than usual. My DD nursed & I expected that to take care of it (she STTN so I am in dire need of that by morning). This helped, but it is still tender. It is just one spot. I have heard of infections and things so now I am worried. I don't feel bad and it is not red. Just a spot of tenderness. Anything I can do to treat this at home or maybe it will go away on it's own?
