There is no problem. It's just like when you sweat, your armpits get a salty discharge as well. Except this is your breasts. This is normal.
Hi,
Nipple discharge is normal and very common when the breasts are squeezed/stimulated and it's rarely a sign of breast cancer.
Milky discharge tastes salty rather than sweet, and may result from high prolactin levels, thyroid malfunction, nipple infection or side effects of medications (e.g. antidepressants)
Take care to avoid nipple stimulation( including frequent checks for discharge) because it can actually make the discharge persist.When nipple stimulation is avoided,most probably the discharge will stop.
When to be alarmed about nipple discharge,is when it happens only on one side, comes out spontaneously( without squeezing),is persistent and bloody or is associated with a lump,nipple or skin changes etc...
If you are worried, make an appointment with your doctor to have it evaluated to clear out any doubt.
Take care...
