Puffiness under the eyes?

I used to use vitamins , and a lot of them. One day i woked up and felled a very hard pain in my lower back, and it lasted 2 days. Now , after a year, I noticed i have Puffiness under the eyes. I got my kidneys and blood checked and i was all ok. I heard that it can be puberty, because I'm 16 years old? Maybe it was realated to that pain? How can I put away that swelling?
