Sore Boobs...What is the actual cause?????

[JosieJo]

re exercise easing sore boobs- lymph flow is poor across the the chest in women as there is a lot between the lymphatic system just under the skin, and the muscles just over the bones. The lymphatic system has no pump and uses the movement of muscles to get things going. Modern firmly supportive and uplifting bras make this issue worse- hence the increase in breast lumps and bumps in Western culture. Fluid build up premenstrually is eased by exercise because it gets that lymph moving- all over the body. Breast swelling can be eased by breast massage (either professionally or a good joobling by a caring friend) if exercise seems too hard!

-just noticed you said before you ovulate...in that case I'd guess its possibly due to an increase of androgens which antagonise oestrogens which can cause some sorts of breast pain...
