Is this an early symptom of varicose veins?

There are many people around me who are worried about varicose veins, so I have been checking my calves in the mirror since I was young. I think I looked at them almost every day when I was doing work that required standing for long periods. When I wake up in the morning, my legs are often swollen and sometimes feel numb, which worried me a lot, but fortunately, I didn't have any symptoms. However, I wonder if this is something that comes with age... Recently, my legs have been swelling quite a bit in the mornings and I’ve been experiencing tingling sensations again. Also, as I’ve lost some weight, I think the blue veins on my calves have become more prominent. My friend already has visible veins that protrude and is receiving injection treatment. Currently, the veins are quite visible, but if the numbness and swelling continue, I worry they might become more noticeable visually. Could this be an early sign of varicose veins?
