Reticular Veins: The Vein Type Between Spider and Varicose
Most people have heard of varicose veins and spider veins, but there's a third, less-talked-about category in between: reticular veins. If you've had spider veins treated before and noticed them come back in the same spot, an untreated reticular vein underneath is often the reason why.
What Are Reticular Veins?
Reticular veins are small, flat, bluish-green veins that sit just below the skin's surface, typically measuring between 1 and 3 millimeters in diameter. That puts them squarely between the two more familiar categories: larger than spider veins (usually under 1 millimeter), but smaller and flatter than varicose veins (generally 3 millimeters or more, and visibly raised above the skin).
Unlike varicose veins, reticular veins don't bulge, and unlike the fine web-like pattern of spider veins, they tend to appear as slightly larger, more diffuse bluish patches, often behind the knee or on the outer thigh.
Why They're Called "Feeder Veins"
Reticular veins often connect to and supply smaller spider veins on the surface, which is why they're commonly referred to as feeder veins. This matters practically: if a cluster of spider veins is treated with sclerotherapy but the reticular vein feeding it is left untreated, the spider veins can reappear in the same area within months, because the underlying pressure source was never addressed. For durable results, a vein specialist will often check for and treat feeder reticular veins alongside the visible spider veins.
Symptoms
Reticular veins are frequently symptom-free and are addressed for cosmetic reasons alone. When symptoms do occur, they're generally milder than varicose vein symptoms and can include:
- Mild aching or heaviness in the area
- Local tenderness
- A burning or itching sensation over the vein
They don't carry the same risk of complications, such as skin ulcers, that larger varicose veins can, though the same underlying cause — weakened vein walls and increased pressure — links all three categories.
What Causes Reticular Veins?
The contributing factors overlap heavily with spider and varicose veins: genetics, age, hormonal changes (including pregnancy and menopause), prolonged standing or sitting, and excess body weight all play a role. Sun exposure has also been associated with reticular and spider veins on areas like the outer thigh, likely through its effect on skin and blood vessel elasticity over time.
How Reticular Veins Are Treated
Sclerotherapy
The standard treatment is sclerotherapy, where a solution is injected directly into the vein, causing it to collapse and fade as the body reabsorbs it over several weeks. Because reticular veins are larger than spider veins, they sometimes respond better to treatment and can even make nearby spider veins easier to treat afterward once the feeder source is addressed.
Laser Treatment
Laser treatment is more commonly used for spider veins, but can be used on smaller reticular veins in some cases, though sclerotherapy remains the more established option for this size of vein.
Graduated Compression Stockings
While compression won't remove a reticular vein, it supports overall circulation and can help reduce the mild aching some people notice, especially after a procedure.

When to See a Doctor
Reticular veins are rarely urgent, and many people choose to leave them untreated if they're not bothered by their appearance. It's worth a doctor's evaluation if a vein becomes suddenly more prominent, painful, or is accompanied by skin changes, since these can occasionally signal a more significant underlying vein issue worth ruling out.

Frequently Asked Questions
Are reticular veins the same as spider veins?
No. Reticular veins are larger (1-3mm vs under 1mm for spider veins), flatter, and bluish-green rather than red or purple. They often act as feeder veins that supply spider veins on the surface.
Do reticular veins need to be treated?
Not necessarily — many people leave them untreated for cosmetic reasons. However, treating them can help prevent nearby spider veins from reappearing, since reticular veins often feed them.
How are reticular veins treated?
Sclerotherapy is the standard treatment, using an injected solution to collapse the vein. Laser treatment is used less often for this vein size, though it's an option in some cases.
Can reticular veins turn into varicose veins?
They're a different, generally smaller category, but they share the same underlying cause as varicose veins: weakened vein walls and increased pressure. Whether one progresses toward the other varies by individual.
