You may notice veins on your shin if you exercise a lot or are on your feet for most of your day.

It is not uncommon for them to be normal veins as a result of your muscles needing more blood supply.

But unfortunately for others, they can be an extension of varicose veins from other regions and be abnormal veins.

Especially if you already have noticed varicose veins in other regions. You will  find they become larger and more prominent as time goes by… but, luckily, they can be treated.
