I am still BF DS2 (3 in September), so I'm putting this problem in this section, although I don't think the problem is bf-related.
Yesterday afternoon my left (better) breast was aching a bit. This morning it was worse. DS2 fed well, which has helped some, but it is still sore.
The discomfort isn't at the surface, there's no redness, I don't think it's a blocked duct or mastitis. The tenderness is well under the surface, maybe in the milk ducts? It doesn't hurt all the time, just if nudged, or if I go over a bump in the car etc.
It's not agony, it's just unnerving.
Could I have just bruised something? I took a dose of iboprofen this morning, in the hopes that would help, maybe it has ...
I've convinced myself a couple of times that there's a lump in there, but it doesn't really feel different from the other breast.
