Tiny, dark spider veins on thighs & large varicose veins behind my knees, any treatment besides surgery??

I'm sick of my spider veins, and as I'm getting older, they are progressively getting worse!! (I'm only 27) I would still like to wear shorts in the summer, but it has gotten really bad :( Is there anything I can do to hide them, or fade them, perhaps? I know there's surgery procedures, but that is only if they are hurting or bulging...etc. Thank God I'm not at that stage, yet..!? Maybe any pill I can take, I DUNNO! I have pale, thin skin as well, so in fact, ANY vein throughout my body shows, and it's embaring. (especially behind my knees...) Any suggestions would really help. Thanks
