Thread veins on legs, also known as spider veins, are small, visible blood vessels that appear just beneath the surface of the skin. Typically red, blue, or purple in colour, they can look like fine lines, webs, or branches. While thread veins are not typically harmful, they can have a significant impact on confidence and self-esteem, which is why many choose to have them treated.

 

What Causes Thread Veins on Legs?

Thread veins in the legs develop when small veins become damaged, causing blood to collect in the area.

Common causes include:

• Genetics
• Hormonal changes (especially in pregnancy or menopause)
• Prolonged standing or sitting
• Sun exposure
• Trauma or injury to the area
• Age-related weakening of blood vessels

 

Symptoms of Thread Veins

While often painless, thread veins can occasionally cause:

• Mild aching or burning sensations
• Localised itching
• Increased visibility after standing for long periods

If you notice discomfort or your thread veins developing, it may be time to seek advice from a specialist. At your VeinCentre consultation, your consultant will conduct a thorough scan to get to the cause of your problem veins and create a tailored treatment plan, just for you.

The most common and effective treatment for thread veins on the legs is Microsclerotherapy, but we can also offer Thermocoagulation treatment for small red veins on the legs.
