I never had issues with veins, compared to the other kids in high school, which could get to the point of making them go up and down like a thermometer by flexing their hands. When I see them getting big in my hands, I know it's time to start moving and get the blood circulating again.
The bad issue is that although they don't bulge, they have started to appear in my chest and one in my face after losing so much fat. Yep, it sucks.
