Could these symptoms also be related to varicose veins?

Sometimes my legs feel very numb. When I was young, it was a bit funny because I felt like electricity was running through the soles of my feet.

I found it interesting to feel a dulling sensation of pain, but thinking about it, I wonder if this is also related to poor blood circulation.

I often get cramps in my legs and have woken up several times because of it. Are these also related to varicose veins?

It's a feeling I want to have. Since this year, my health has been quite poor, so I've become interested in things I usually didn't pay attention to, and everything else.

When I hear it, it seems related to my physical condition. I've heard a lot from those around me, but what exactly are the symptoms of varicose veins?
