Thread veins and spider veins are small, visible blood vessels that sit just beneath the surface of the skin. They are usually red or purple in colour, and more often than not they don’t cause any harm to the patient, although they can ache in certain cases, and in others can look a bit unsightly.
When thread veins affect the legs, they can sometimes cause an aching sensation after standing or walking for longer periods of time. In general, they occur over time when a blood flow is disrupted by a back up of blood within the vessels as a result of long-term damage and malfunction within the vessels themselves. Thicker, more prominent veins and usually referred to as thread veins, whereas smaller instances are known as spider veins due to the branching, web-like appearance, which can cause distress for some sufferers. Sclerotherapy is a non-invasive, injectable treatment for patients looking to eliminate unsightly thread veins for good, leaving behind skin that is beautifully clear and blemish-free.
