How is CVI treated?

After hearing about CVI, the next question is usually what treatment looks like. Here is the plain starting point.
Where treatment begins
The publisher my.clevelandclinic.org says: "Treatment for chronic venous insufficiency involves lifestyle changes and compression therapy."
Those are the two pieces named in that sentence. Your provider decides how they apply to you and whether anything more is needed.
Pages to explore
The Society of Interventional Radiology page on superficial venous disease and chronic venous insufficiency is one place to start. MedlinePlus covers varicose veins and spider veins. From my.clevelandclinic.org you can read about edema and about endovenous ablation. Readers in the townships of Frankfort and Rich can use them to prepare questions.
A simple next step
Ask your provider to explain lifestyle changes and compression therapy in everyday terms, and to say which one to start with.
A methodical diagnostician begins with the simplest steps and moves on only when the person in front of them needs more.
