Swelling in the legs is more than just annoying — it can feel tight, uncomfortable, and even painful. While it’s often harmless, sometimes it signals an underlying issue. Here's what could be going on and how you can take action.
Swelling Usually Starts in the Lower Legs
Gravity causes fluid to collect in the lowest parts of the body, especially the ankles and lower legs. It’s often the first visible sign of retention.
You Can Test It Yourself at Home
Press your finger gently into your shin for a few seconds. If a dent remains after you release, it’s likely fluid buildup — also known as edema.
Swelling in Both Legs Often Has Internal Causes
If both legs are swollen, it’s often due to conditions like heart issues, kidney problems, hormonal shifts, or medication side effects — not a leg injury.

One Leg Swollen? Look for a Local Cause
If only one leg is affected, it could be something localized like a blood clot, inflammation, or varicose veins. In that case, don’t wait to talk to a doctor.
Inactivity Can Make It Worse
Long periods of sitting or standing still reduce blood flow from the legs back to the heart — which increases pressure and causes fluid to leak into tissues.
Movement Activates Your Leg’s “Venous Pump”
When you move, your muscles help push blood upward against gravity. This keeps circulation flowing and reduces the chances of fluid collecting.
Compression Socks Can Help
Tight-fitting medical socks can support blood flow and prevent excess fluid from accumulating in the legs — especially useful for long flights or varicose veins.

Elevating Your Legs Works — Fast
Raising your legs above heart level for 15–20 minutes can help gravity drain excess fluid and relieve swelling quickly.
Cut Back on Salt
Too much salt causes the body to hold onto water. Reducing sodium — especially from processed foods — can noticeably reduce swelling.
In Some Cases, Water Pills May Be an Option
If lifestyle changes don’t help, a doctor may recommend diuretics (water pills). But these are typically used only when swelling is linked to heart, liver, or kidney conditions.
