Long travel or sitting for hours can leave your legs feeling heavy. Most people assume it's just stiffness and wait for it to settle. In many cases, it does. But when the discomfort stays, or you notice swelling in one leg, it may need attention. Why does long sitting increase risk? When you sit for long periods, blood flow in the legs slows down. This can sometimes increase the chances of clot formation. What symptoms should you not ignore? Pain in one leg, swelling, warmth, or a tight feeling that doesn't improve with movement. Is it always a blood clot? Not always. But it's important to rule it out early rather than assume it's minor. How is it diagnosed? A Doppler scan is commonly used. It is quick and helps identify whether the issue is related to a clot or circulation. Who should be more careful? People with long travel routines, sedentary work, or existing vein issues. What should you do if symptoms persist? That's when patients often look for an interventional radiologist in Pune for further evaluation. Not every leg pain is serious. But the ones that are often start this way. If your symptoms haven't settled after a few days, you can consult Dr. Santosh B. Patil at Expert-IR and get a proper evaluation before it progresses. 3-
