Question] Inside of the ankle. Overall, there are tiny blood vessels in the leg...

This is an inside ankle photo. The veins appear bluish and enlarged. The area inside the knee and ankle, as well as the starting point of the thigh, shows severe bluish venous congestion. Additionally, it seems that the number of tiny blood vessels is gradually increasing. Are these early symptoms of varicose veins?

I'm curious whether the prescribed medication is effective at this stage.
