Spider veins vs varicose veins: what’s the difference?
Although the differences between varicose veins and spider veins are significant (both in appearance and in severity), they are often mistaken for one another. To someone who hasn’t studied vascular health, they may simply look like veins that have changed colour or shape. In reality, recognising which one you’re dealing with matters for both treatment and long-term health.
In the following guide, we break down what each condition truly represents, how to recognise it, what symptoms to watch for, and which treatments are available today. So, if you’ve ever wondered whether the veins on your legs are spider veins or varicose veins, keep reading our article to find out.

What are varicose veins?
Varicose veins are enlarged, swollen veins caused by improper blood flow. They develop when the valves inside the veins (tiny structures that act like one-way gates) fail to close properly. When these valves weaken, blood begins to flow backwards and pool within the vein. Over time, the pressure stretches the vein walls, causing them to twist, bulge, and rise to the surface of the skin. This is why varicose veins often appear raised and rope-like.
What do varicose veins look like?
You can usually identify varicose veins through several visible characteristics:
- They appear raised above the skin surface
- Often look twisted or bulging like cords
- Usually blue, dark purple, or green in colour
- Most commonly found on the legs and behind the knees
- Can be felt easily when you touch the skin
Because they are caused by venous insufficiency, varicose veins can progress over time if not treated.
What are spider veins?
Spider veins (telangiectasias) are much smaller and closer to the skin surface. They form when tiny blood vessels dilate or break, creating delicate web-like lines. Unlike varicose veins, they do not bulge or twist, and you typically cannot feel them through the skin. They are called spider veins (or thread veins) because of their thin, thread-like appearance (often red, purple, or blue), resembling a small spider web or tree branches spreading out. Spider veins are generally harmless from a medical perspective and are usually considered a cosmetic concern, though they can still cause emotional distress for many people.
What are the symptoms of varicose veins?
Varicose veins often come with physical symptoms caused by poor blood return and increased pressure inside the vein.
- Leg heaviness and tiredness (due to blood pooling rather than circulating efficiently)
- Aching or throbbing pain (especially after long standing)
- Swelling around the ankles
- Burning or itching around the affected veins
- Night cramps or restless legs
- Dry or irritated skin over the veins
These symptoms often worsen toward the end of the day or after long periods of sitting or standing.
What are the symptoms of spider veins?
In the case of spider veins, here’s the good news: they are usually painless. They rarely cause discomfort or swelling, and most people notice them only because of their visible pattern. So, the main “symptom” is: a web-like pattern of fine red, blue, or purple veins, most commonly on the legs or face.

What are the risk factors for developing varicose veins or spider veins?
Both conditions can run in families. If parents, grandparents or siblings have varicose or spider veins, your risk is naturally higher. Also, it is important to note that up to one-third to half of patients with spider veins have an underlying varicose vein condition. This means that even if only small spider veins are visible externally, there may be deeper venous insufficiency requiring treatment. A routine vascular assessment is a wise step, especially if you have a family history.
The differences between varicose veins and spider veins: an overview
So far, we have seen what the veins look like in each type of condition and what the risk factor is. Below, we have summarized the main differences and similarities to make them easier to follow:
| Characteristic | Varicose Veins | Spider Veins |
|---|---|---|
| Medical impact | Can cause symptoms + complications | Mostly cosmetic |
| Appearance | Bulging, twisted, thick | Thin, flat, branching lines |
| Colour | Blue/purple/green | Red/blue/purple |
| Location | Legs (most common) | Legs + face |
| Symptoms | Pain, heaviness, swelling, itchiness | Painless |
| Treatment urgency | Often recommended | Optional, aesthetic choice |
How are varicose veins treated?
Varicose vein treatment is no longer synonymous with surgery. Today, patients have access to minimally invasive (and even non-invasive) approaches. Below is a simple breakdown of the most common treatments.
SONOVEIN (HIFU — High-Intensity Focused Ultrasound)
This is a non-invasive treatment that doesn’t require catheters, needles inside the vein, or incisions. Ultrasound energy is focused on the vein wall, heating it from the inside. The heat destroys the vein, which gradually closes and is naturally absorbed by the body.
EVLA — Endovenous Laser Ablation
A laser fibre is inserted into the diseased vein. Heat from the laser seals the vein wall, and the body later absorbs the closed vessel. This is done under local anaesthetic, usually within 20–30 minutes per leg.
EMWA — Endovenous Microwave Ablation
This one is similar to EVLA, but instead of laser energy, microwaves generate heat to close the vein. It doesn’t require direct contact with the vein wall and involves fewer safety precautions. Results are comparable to laser, representing a modern and effective option.
Foam Sclerotherapy
The doctor injects a medication in foam form into the vein, irritating the vein wall and causing it to collapse. Over time, the body absorbs and eliminates the damaged vessel.
What are the treatment options for spider veins?
Spider veins require different treatments as they are superficial and usually painless.
Microsclerotherapy
Similar to foam sclerotherapy used in varicose veins, but performed on much smaller vessels. A tiny needle delivers a solution that collapses the vein, which later fades or disappears.
IPL (Intense Pulsed Light)
This one is a light-based treatment that targets pigment in the vessel. The heat damages the vein, and with time, it fades naturally. Mild redness may occur, but recovery is quick, and results appear gradually over several weeks.
Varicose veins complications
Unlike spider veins, varicose veins can progress if left untreated. Complications may include:
- Leg ulcers — painful wounds caused by poor circulation. When the condition is complicated with venous ulcers, pain can be severe, with reduced ability to walk and work and an unpleasant odour.
- Superficial thrombophlebitis (clot + inflammation)
What happens if you ignore spider veins?
Spider veins rarely cause physical damage. They may, however, affect confidence, leading to self-consciousness or reluctance to wear shorts or skirts. From a medical perspective, spider veins are usually harmless. But considering that up to half of spider-vein patients have underlying venous insufficiency, a consultation is always a wise step.
Other FAQs about varicose veins and spider veins
1. Can varicose veins disappear on their own?
No. Once the vein walls are damaged, they don’t repair themselves naturally. Treatment is required to remove or close them.
2. Can exercise improve varicose or spider veins?
Movement boosts blood circulation and may reduce symptoms, but it won’t eliminate existing damaged veins.
3. Are compression stockings helpful?
Yes. They improve venous return and reduce swelling, but they won’t treat varicose veins.
4. Can spider veins turn into varicose veins?
Not directly, but they may indicate early venous insufficiency. A vascular assessment is always recommended.
Do you suspect you have varicose veins or spider veins?
If you’ve reached this point and many of the signs feel familiar, it may be time to speak with a specialist. A medical consultation can clarify exactly what type of venous condition you’re dealing with and, more importantly, which treatment path is most appropriate for your needs.
