Bruises or spider veins? What to do? (Photo)

From the pictures posted it is difficult to say for certain. Although these have the appearance of bruising, small clusters of little veins can sometimes appear similar.  If these are in fact veins, you can see what is called blanching (clearing of the area) by applying pressure over the area that is then followed by inflow and refilling of the area.  If it is bruising then it wont blanch. Also, bruises will go away within a few weeks but veins will persist. Only way to tell, would be to either wait to see if they go away or do a formal in person assessment. In either case, I do recommend you use compression stockings at work since you are on your feet all day. This will help maintain healthy veins healthy and prevent rapid worsening of any unhealthy veins. 

To be active is a great healthy habit to strengthen your muscles and maintain good circulation. Healthy leg veins contain valves that open and close to help the return of the blood back to the heart. By looking at the photos, it is very limited what can be said; however, I recommend an evaluation with a vein specialist if you are concerned about veins or venous reflux disease.  What venous reflux does is that the affected valves that keep blood in the veins flowing out of the legs and back to the heart, no longer function. This causes the blood to pool in the legs forming varicose veins and leading to many other signs and symptoms. Consider an evaluation with a vein specialist who you can trust that can examine your venous system with ultrasound.Best, 

The posted pictures are not easy to decipher.  If you have small veins then they can be treated by topical laser or sclerotherapy.  If bruising then they will resolve spontaneously over several weeks.  See a vein specialist.
