An estimated 80 million Americans suffer from a vein-related condition. Since most veins lie deep under the skin’s surface, vein disorders are not always visible to the naked eye. As a result, it’s important to be aware of the symptoms that might reveal an underlying vein condition. If you’re experiencing pain, fatigue, heaviness, cramping, or restlessness in your legs, you should seek expert consultation. Today, a venous duplex scan is used to view internal images of your veins, even the veins beneath the muscles (deep veins). The ultrasound exam, which is painless and takes fewer than 30 minutes, allows a trained specialist to examine your venous system to determine if your symptoms are connected to a vein-related condition. The good news is that many vein conditions can be easily treated. Often, you just need to look beneath the surface to get moving in the right direction.
