Leg numbness [varicose veins? early diabetes? hyperlipidemia? What could it be]

I thought the numbness in my leg was due to varicose veins, so I had it checked at a general hospital, and they said it's not in the surgical stage.

Diagnosis of hyperlipidemia with a level of 230 three years ago

I take the medication, but I stop due to allergies.

Again 230

My sister says her cholesterol is high and her legs are numb.

Additionally, I was curious because I feel drowsy after meals, and my fasting blood sugar level is 110.

I maintain a healthy weight and walk over 10,000 steps every day.

Therefore, I don't particularly like meat and generally prefer vegetarian dishes.

Is there a way to resolve leg numbness caused by early-stage diabetes and high cholesterol?
