## Core Concept
Varicose veins are a common condition characterized by enlarged, twisted veins, typically in the legs. The management of varicose veins depends on the severity of symptoms and the presence of complications. Immediate management focuses on alleviating symptoms and preventing complications.

## Why the Correct Answer is Right
Elevation of the limb and application of a compression stocking are often recommended as initial measures for managing varicose veins. This approach helps reduce swelling, alleviates pain, and prevents further venous pooling.

## Why Each Wrong Option is Incorrect
* **Option A:** Typically involves more invasive procedures such as sclerotherapy, endovenous laser treatment, or surgical removal of the vein, which are not immediate management steps.
* **Option B:** May involve diagnostic tests or procedures that are not immediate management steps for varicose veins.
* **Option C:** This option could potentially be a part of management but is less specific and immediate compared to elevation and compression.

## Clinical Pearl / High-Yield Fact
A key clinical pearl is that for patients with varicose veins, especially if they are experiencing pain or swelling, elevating the legs above the level of the heart and using compression stockings can provide significant relief. This is a simple yet effective initial management strategy.

## Correct Answer: D. Elevation of limb.
