Hi,
If the vein looks like a blue sausage, the vein is damaged. You need to see your doctor or dermatologist. They will inject them with a solution that will cause them to close up. The remaining matter will be absorbed by the body.
These veins aren't the same that you get from bodybuilding. I'am very vascular from my own training, but they are definately not the same type.
Anyways, once the doctor is done injecting them, they wrap them up and recommend that you don't stand on your feet too much or don't do anything strenuous for a few days to weeks, depending on the severity of the procedure.
