Given the data you provided, an assumption is made that you had your ovaries removed too, when the hysterectomy was performed. If this is correct, then the symptoms you reported might be related to inadequate function of the pituitary gland. Oxytocin is one of the hormones of the pituitary gland. It helps to release the milk from the nipples. Perhaps the secretion from the nipples is not really human milk, but something else that is released with the help of oxytocin. That would explain the normal values of prolactin. If the problem is located only in its posterior part, then effects from inadequate secretion of the other hormones might be missing.


You might want to have laboratory tests for oxytocin as well as a computer scan or other imaging methods in order to check the condition of the pituitary gland.
