Sore nipples and lumps behind nipples

There's other things that can cause lumps. If you have any concerns at all, it's always best to see a dr.

How old are you hun?

Sometimes there are "lumps" that develop while your breasts are developing and this is a naturally occurring phenomenon. Depending on your age this may be quite normal.
