Most people think varicose veins are just a cosmetic problem. Bulgy veins on your legs that look bad in shorts. But the underlying condition, chronic venous insufficiency or CVI, affects how blood moves through your lower body. And it tends to get worse over time if nobody addresses it.
CVI happens when the valves inside your leg veins stop working the way they should. Normally those valves keep blood flowing upward, back toward your heart. When they weaken or fail, blood pools in the lower legs. That pooling is what causes the swelling, aching, and heaviness that so many people write off as just getting older.
The early signs are easy to ignore. Your legs feel tired at the end of the day. Your ankles look puffy by evening. You notice some discoloration around your shins or calves. Maybe you get restless legs at night that make it hard to sleep. None of these feel like emergencies, so most people wait.
Waiting is where the trouble starts. CVI is progressive. The longer blood pools in those veins, the more pressure builds. That pressure damages the surrounding tissue. Skin changes happen. You might see brown or reddish patches near your ankles. The skin can become thin, dry, and fragile. In advanced cases, venous ulcers form. These are open wounds on the lower leg that heal very slowly and often come back.
There are a few things that raise your risk. Standing or sitting for long hours every day puts extra strain on those valves. Pregnancy increases the volume of blood in your body and adds pressure to leg veins. Family history matters too. If your parents dealt with vein problems, you’re more likely to develop them. Age is a factor, though CVI can show up as early as your 30s and 40s.
Getting checked is straightforward. A vein specialist will typically do a duplex ultrasound, which is a painless scan that shows how blood is flowing through your veins in real time. It takes about 20 to 30 minutes and doesn’t require any prep. The scan tells the doctor exactly which valves are failing and how much reflux is happening.
Treatment options have come a long way. Most procedures are minimally invasive now. Techniques like radiofrequency ablation and sclerotherapy close off the damaged veins, and your body reroutes blood through healthier ones. Recovery is fast. Most patients go back to normal activity within a day or two.
Practices that handle both the vein side and the cardiac side tend to give a more complete picture of what’s going on. Healthy Living Heart and Vein is one example of a practice that evaluates the full cardiovascular system rather than treating vein symptoms in isolation. That kind of approach matters because vein problems and heart conditions can share risk factors like high blood pressure, obesity, and sedentary habits.
If your legs have been feeling heavy, swollen, or achy for more than a few weeks, it’s worth getting an evaluation. CVI doesn’t fix itself, and catching it early means simpler treatment and better outcomes. The longer you wait, the more those valves deteriorate, and the harder it becomes to reverse the damage.
The communities around The Woodlands, Shenandoah, Spring, Tomball, Magnolia, and Montgomery all have residents dealing with these exact symptoms. Many of them commute or work desk jobs that keep them sitting for hours. Others spend long shifts on their feet. Both of those patterns accelerate CVI. Getting a baseline vein screening in your 40s or 50s is a reasonable step, even if you don’t have visible varicose veins yet.
