Spider veins (fine, web-like red or purple veins that often appear on the legs or face) are extremely common and typically not a cause for concern. For many people, they’re simply a visual issue. That said, in some cases, they may cause mild discomfort or indicate changes in how the veins are functioning, especially if they begin to spread or become more prominent over time.
In this blog, we’ll explore when it might be worth keeping an eye on spider veins, what signs to look out for, and the effective treatments available at VeinCentre to help you feel more comfortable.
What Are Spider Veins?
Spider veins (also known as thread veins) are small, dilated blood vessels that can appear red or blue near the skin’s surface. They usually form due to increased pressure in the veins and are most often seen on the legs and face. While not medically serious in most cases, many people choose to treat them because of how they affect their confidence or physical comfort.
When to Worry About Spider Veins
Most of the time, spider veins don’t require medical attention. However, you should consider speaking to a vascular consultant if you experience any of the following:
• Pain, aching, or burning in the area of the veins
• Swelling in the ankles or legs
• Skin discolouration or irritation around the veins
• Spider veins on your feet that are worsening over time
• A personal or family history of vein problems
Though they’re generally considered a low-risk condition, spider veins can sometimes indicate underlying venous insufficiency, a condition that affects healthy blood flow in the legs. If you have any concerns or are simply looking for peace of mind, our expert vascular consultants are here to help. Don’t hesitate to get in touch for friendly advice and personalised support.
Treatment for Spider Veins
The most effective treatment for spider veins is Microsclerotherapy. This quick, walk-in, walk-out procedure is minimally invasive and requires no general anaesthetic. Using a tiny needle, a solution is injected into the affected veins, causing them to gradually fade over time.
Microsclerotherapy is well-tolerated by most patients, offering visible results with minimal downtime. Many people return to their normal routine the same day, making it a convenient option for those with busy lifestyles.
While cosmetic creams and home remedies may temporarily improve the appearance of spider veins, they cannot treat the underlying issue. For long-lasting results and a noticeable difference in how your legs look and feel, professional treatment like Microsclerotherapy remains the most reliable solution.
