Ulcers are also a potential side effect of venous insufficiency, which can turn into something quite nasty if not properly treated. See below for a list of common vein disease symptoms and the visual illustration of the impact different vein diseases have on your body, including spider veins, venous leg ulcers, hyperpigmentation, and more. This ensures that any problems are nipped in the bud at the first sign of problems. And luckily, it is typically something that can be treated with a minimally-invasive outpatient procedure at a vein clinic near you.
