thanks for your query
look both thyroid and pituitary gland
abnormality can lead to similar problems like galactorrhoea
sply can lead to this. For this you need thyroid hormone supplementation.
on the other hand pituitary abnormality secondarily may lead to hyperprolactinoma that may give rise to excessive milk like discharge and for that you have to take bromocriptine
excessive secretions had lead to soreness of breast.
again you have to exclude underlying mass lesion in the breast for that you are been rightly suggested a mammography
because it can detect the mass.
dont be worried. after proper diagnosis appropriate treatment will relieve your symptoms.
