Clinical pictures are so helpful - thanks for providing. On initial inspection, it looks like you have an enlarged varicose vein rather than a reticular / spider vein. This vein can still be easily treated with targeted ultrasound guided foam sclerotherapy which is relatively painless and quick to perform with minimal complications. However, prior to consideration of any vein treatments at "Professor Mark O'Donnell Varicose Veins and Vascular Surgery Clinic Belfast - Northern Ireland - Ireland", it is essential to have a venous duplex scan to exclude major truncal varicose veins which may require additional treatment with radiofrequency ablation to afford a better treatment outcome and enhance longevity.
