Veins on my hip and the back of my legs - will they get worse overtime? (photos)

Lauren, Thank you for sending photos. The photo you shared show normal reticular dermis veins. These veins are normally present on everybody's legs. As you point out your skin is fair and rather translucent. This is healthy, but it does allow your normal veins to be more visible. There is no way of knowing for sure whether they will turn into varicose veins. Varicose Veins are very common, so there is always a chance you could develop varicose veins. I recommend that you stay as healthy and active as you can. Wishing you the best, Dr Wright.
