I have veins on top of my foot, one day all of a sudden they were filled with blood, swollen and lots of them. like varicose, I am ashamed to wear flip flops now or anything that will expose the top if my foot. I dont understand what is causing this. I had an ultrasound doen to my legs, no clots no leakage. I just want my feet back =( Any advice? should I see a podiatrist?
