Why Do My Legs Feel Heavy? Understanding Venous Insufficiency

Have you ever come home at the end of the day and noticed your legs feel like they’ve been weighed down with sandbags? You’re not alone. Many people describe their legs as heavy, tired, or achy, especially after standing or sitting for long periods. While it’s tempting to brush this off as just being “on your feet too much,” the truth is that these symptoms could be an early sign of chronic venous insufficiency (CVI).

So, what exactly is CVI? It all comes down to the way your veins work. Healthy leg veins contain one-way valves that push blood back toward the heart. But when those valves weaken or stop working correctly, blood can pool in the legs instead of moving upward. This backward flow, called reflux, creates pressure in the veins, which leads to that all-too-familiar heaviness.

Other symptoms that may tag along with heavy legs include:

• Swelling around the ankles or calves
• Aching, throbbing, or cramping sensations
• Restlessness at night
• Skin discoloration, itching, or dryness
• Visible varicose or spider veins

The good news? CVI is treatable—and the earlier you address it, the easier it is to manage. Lifestyle changes like elevating your legs, wearing compression stockings, staying active, and maintaining a healthy weight can make a big difference. But if symptoms persist, it’s time to consider medical treatments such as radiofrequency ablation (RFA), sclerotherapy, Varithena®, VenaSeal™, or phlebectomy. These minimally invasive procedures are highly effective at restoring proper circulation and relieving symptoms.

If your legs often feel heavy, achy, or swollen, don’t ignore it. Those signals could be your veins asking for help. Getting a simple ultrasound exam can reveal what’s going on beneath the surface—and guide you toward lasting relief.
