Pain in one breast - any advice?

[coffeeandcream]

I have a constant, low level achy type pain in one breast, sort of all under the nipple. It doesn't get worse when DS feeds and I have no other symptoms.

Any ideas what it might be? I thought maybe mastitis, but I don't have any fever type symptoms.

Thanks in advance

A blocked duct maybe? Try massaging in a hot shower.
Are there any red patches at all?
