Varicose veins are a common condition that affects millions of people worldwide. They are often diagnosed using a Doppler ultrasound scan, which helps assess the blood flow in the veins and detect any abnormalities. However, many patients get confused when they hear that nerves are not visible on the scan or when they notice veins becoming more prominent after wearing compression stockings.
So, what's really happening? Let’s break it down in simple terms.
What Is a Doppler Scan and What Does It Show?
A Doppler ultrasound scan is a non-invasive imaging test used to check the flow of blood through veins and arteries. It's commonly used to diagnose varicose veins, deep vein thrombosis (DVT), and other vascular issues.
Important to note:
Doppler scans focus on blood vessels — primarily veins and arteries.
Nerves are not visible on Doppler scans because they don’t carry blood the same way vessels do.
So if your report says that nerves are not visible — that’s normal. It doesn’t mean anything is wrong with your nerves.
What Are Varicose Veins?
Varicose veins are enlarged, twisted veins, most commonly found in the legs. They occur when the valves inside the veins become weak or damaged, causing blood to pool and the vein to bulge.
Common symptoms include:
Visible bulging veins
Leg pain or heaviness
Swelling and itching
Skin discoloration
Why Wear Compression Stockings?
Compression stockings are a first-line treatment for managing varicose veins. They work by:
Improving blood flow
Reducing swelling
Preventing blood from pooling in the veins
Minimizing discomfort
They come in different compression levels (measured in mmHg) and need to be properly fitted by a medical professional.

Now, the Big Question: Why Are Veins More Visible After Wearing Compression Stockings?
If you’ve started wearing compression stockings and suddenly notice veins becoming more visible, it can be alarming. But here are some possible explanations:
1. Improved Circulation
Compression stockings help push blood from the surface veins into deeper veins. As circulation improves, some superficial veins may appear more prominent temporarily — especially if you're observing your legs more closely.
2. Skin Tightening Effect
Wearing tight stockings compresses the skin and surrounding tissue, making underlying veins appear more visible, especially in thinner skin areas.
3. Wrong Size or Compression Level
Stockings that are too tight or worn incorrectly can cause blood to pool in unintended areas, making veins appear more pronounced. It’s important to ensure your stockings are medically prescribed and fitted.
4. Not Actually “Nerves”
Sometimes people confuse visible veins with “nerves coming out.” Nerves do not bulge or become visible. What you're likely seeing are smaller surface veins or even newly distended veins as a result of pressure redistribution.

Should You Be Concerned?
Not necessarily — but it’s worth monitoring. If:
The visibility of veins increases significantly,
You experience pain, tingling, or numbness,
There’s any skin discoloration or ulceration,
Then it’s best to consult a vascular specialist. They may recommend a follow-up Doppler scan or adjust your compression therapy.

Final Thoughts
It’s completely normal for nerves not to show up on a Doppler scan — that’s just how the test works. And while it may seem odd to see more visible veins after starting compression stockings, it’s usually a temporary or harmless effect of improved blood flow and tissue pressure.
However, always listen to your body. If you’re unsure or uncomfortable, don’t hesitate to seek professional guidance. The goal of any treatment is to make you feel better — not more anxious.
