Some of your symptoms might be related to varicose veins, which are enlarged veins that can vary in color and shape. They often cause discomfort and dull pain. Prolonged standing can worsen this pain. The numbing sensation you felt might be due to insufficient blood flow through the veins. To improve circulation, try elevating your legs when lying down and wearing compression stockings. Additionally, regular exercise and avoiding excessive sleep can help. Keep an eye on your symptoms, and if the pain worsens or becomes severe, visit an orthopedist.
