Maybe this has been posted somewhere before...or maybe this is the wrong forum...i have no idea, but here goes:

On my forearm below and above the elbow you can see my entire vein system at work. They're pretty blue and I can trace them as far up as my palm, though they gradually fade away at this point. I'm pretty sure theyre not "varicose" veins since they aren't little explosions of veins randomly assembled; they ARE all my veins. Since i was a teen I noticed this phenomenon, but they werent as evident back then. In fact i barely even noticed how much darker they're looking until someone recently pointed it out to me, then i got all freaked out about it.

Is this something i should be worried about, either now or in the long term?

thanks in advance
