Why varicose veins itch (and what helps)

Itching is a common varicose vein symptom

Itching around varicose veins is very common. It can range from mild irritation to a persistent, distracting itch that is worse in the evening. In many cases it reflects pressure and inflammation in the skin caused by venous reflux.

Why varicose veins can make the skin itch

When valves in leg veins are leaky, blood can pool and pressure rises in the lower leg. Over time, that pressure can affect the tiny blood vessels in the skin and trigger inflammation.

Common reasons itching happens

• Dry skin: swelling and irritation can make the skin drier and more sensitive.
• Venous eczema: inflamed, itchy, red or scaly patches, often around the ankle.
• Skin stretching from swelling: tight, puffy skin can itch.
• Heat and standing: symptoms often worsen later in the day as pressure builds.

What usually helps (practical steps)

The aim is to calm the skin and reduce the pressure that is driving the irritation.

Try these steps in order

1. 1
   Moisturise daily, ideally after a shower and again at night

   A simple, fragrance-free emollient is often best.

2. 2
   Avoid very hot baths and harsh soaps, which can strip oils and worsen dryness

3. 3
   If swelling is part of the problem, elevate your legs for short periods during the day

4. 4
   Consider compression stockings if itching comes with heaviness or swelling

   They can reduce venous pressure and skin irritation.

5. 5
   If you have a red, scaly patch that keeps returning, it is worth getting it assessed rather than repeatedly scratching it

When itching suggests skin changes worth checking

Most itching is not dangerous, but persistent itching around the ankle can be an early sign of skin changes linked to long-standing venous reflux.

Signs to take seriously

• A persistent red or brown patch near the ankle.
• Skin that becomes shiny, tight, or thickened.
• Weeping or crusting skin (especially if it keeps returning).
• A small wound that is slow to heal.

How a duplex scan helps

A duplex ultrasound scan shows whether there is reflux in a main trunk vein or other veins feeding the area of skin irritation. If there is a clear source of reflux, treating that source can improve symptoms and reduce the chance of progressive skin changes.

Next steps

If itching is frequent, or you are seeing skin changes around the ankle, a specialist assessment with duplex ultrasound can clarify what is driving it and what treatment would realistically help.
