I have noticed that by the end of the day the veins particularly in my feet, hands annd arms seem to bulge, ewwwww, whats up with this?

the more exertion, the more blood flow. Check out the veins on most atheletes. As to the feet, you ought to be sure it's just that, and not related to varicose veins. The latter implies problems with the valves in the veins, which generally happens in legs, not arms. It can lead to secondary problems such as chronic swelling, skin breakdown, blood clots. So people with varicose veins in their legs are well-advised to use some sort of support hose. Talk about "ewwwww!"

Thanks sid, I have been working out again after a long break, running and weights, so that is most likely the cause. Mmmm, support hose, how sexy!!!
