Veins In Legs

Recently, I've Been Noticing That I Have A Lot Of Veins In My Legs That Are Very Visible. A Few Of Them Bulge A Little, But For The Most Part, They Just Look Blue. I Don't Recall Ever Being Able To See Them Quite So Well In The Past, And Recently, They've Also Started To Hurt A Little Bit. Not Only Am I Troubled By The Discomfort They Cause, But I'm Also Really Embarrassed. I'm Only 22 Years Old And I Don't Want This To Be Something That Only Gets Worse As I Get Older. Any Ideas What This Might Be Or How I Can Get Rid Of It?
