What's the difference between poor lymphatic flow vs varicose veins?

I went to see the doctor about what I thought was varicose veins. She explained that these were not varicose veins but poor lymphatic flow. She said that injecting these would only make the problem worse. These are barley visible and it's a cosmetic thing as I am under 30. Has anyone else had this problem and if so how do you get it treated. I'm in good shape, healthy, workout 4-5 times a week and eat right (try to at least).
