I'm wondering if it's varicose veins.

Hello, I am leaving a message because I am curious about symptoms of varicose veins in this event. First, my symptoms are that when I stand for a long time, pain starts from my calves and rises up to the groin and thighs. If I look at my legs, I can see a bulging vein on the inside of my ankle, which is easily visible externally. So, I suspect this might be varicose veins. If it is varicose veins, I want to know whether it can be treated with medication alone or if it requires procedures or surgery. I am worried and wondering if I am overthinking this.
