High Prolactin Levels, Not Pregnant

Anyone else have high prolactin levels? I've been lactating since I was about 16 (almost 10 years ago now)! It's not like a lot, but when I squeeze my nipples, it comes out. At first I thought it was a side effect from a medicine I was on but it's been years since I was on that medication, and it still hasn't gone away! Why might this be happening? I heard high prolactin can impair fertility and that it can be associated with PCOS...are these things true? And do you know of any methods of reducing prolactin? Thanks!
