I Have Veins That Are Very Pronounced In The Lower

I have veins that are very pronounced in the lower front area of my legs,some other areas of concern with this is , every morning when first getting out of bed I have tingling at the bottom of my feet as soon as they hit the floor.
Recently I just started jumping on the trampoline and my legs seems too feel very heavy and tired after only after a few seconds. Should I have reasons to be overly concerned?
