That does sound like
varicose veins. Often these are harmless and you can self treat but do show
them to your doctor on your next visit. Prop your legs up and elevate them, you could try regular exercise which helps (if you are cleared for activity), losing some weight if you need to and compression stockings can help keep them from getting worse. If they do get worse or they really worry you, then see your doctor now about them. There are good treatments these days. https://www.mayoclinic.
