Pituitary gland problems

Hi there! I'm a 33 y.o female with what I suspect is a pituitary gland problem. 1 year ago I started experiencing headaches on the left side of the head (left temple). The pain is constant and is accompanied by a buzz in the left ear. Sometimes the pain sometimes extends to the left eye ( like a pressure on the eye) and i wake up with a swollen upper eyelid every morning. Also, i have experiences signs of a hormonal imbalance: very greasy skin on my face ( forehead, nose and chin), pronounced hair loss, swollen breasts and abdomen and weight gain (without eating much). And no, i'm not pregnant. The endocrinologist run some tests and the pituitary hormone prolactin was a bit high, while progesteron and testosterone were low. Dr said it's not too serious, so i shouldn't worry. However the constant headache bothers me and i'm just not feeling like myself. The problems started after i had a sinus and ear infection and then an infected wisdom tooth infection, so i'm wondering if it's all. Any ideas what i could do? I've been trying some remedies and they have helped, but nothing seems to eliminate the headache completely. Thank you in advance for your help.
