out of the blue her left breast swelled, and two elongated lumps in her breast, they were exremely hard to the touch, the whole breast in general was harder than the other. And the hard spots on her breast when you'd touch them it'd hurt so bad she'd have tears come out of her eyes, she couldn't walk cuz her brest would hurt, she was in bed for about 5 days. it all went away within 2 weeks. Now a few months went by, literally this never repeated, and i touch her breast, all clear no lumps nothing. what could've cause that?
