Oily Discharge From Skin, Bright Forearms, Breast Leakage. Causes For Symptoms?

Today for the first time my skin started leaking oil. Literally my forearms where bright all of a sudden. I rubbed it off thinking I had spilled something on me, and half a minute later they where covered in oil again. About 5 minutes later left breast was leaking as well and it trespassed my bra and my shirt was all oily. I dont know what this means. 2 hours have passed and it hasnt happened again, but what is it?
