Good day! One breast is noticeably larger than the other, and strange stabbing pains (rarely, not often) started in the larger breast than the other. There are no lumps, there are no pains during feeding, the nipple doesn't hurt during feeding and generally. But there are such covering strange sensations... What is it? Why so? Who has encountered this? What would you recommend? Thank you in advance for your answers ??❤️
