Compression stockings can help when the legs feel heavy or swell, especially during long days of standing or sitting. The two things that matter most are the pressure level and the size. A good stocking feels snug, but it should not cause pain, numbness, or coldness in the foot.
What they are used for#
Compression stockings support venous return and can reduce fluid pooling in the lower legs. That is why they are often used for work shifts, travel, or pregnancy-related swelling. They can ease symptoms, but they do not treat the underlying cause by themselves.
How to choose pressure#
Light compression is often enough for everyday comfort or mild swelling prevention. Moderate compression may suit clearer swelling or symptomatic varicose veins. Strong compression should usually be chosen with healthcare guidance so that both the need and the safety are checked.
If you are unsure, starting with a lighter option is often better than buying something too strong and never using it.
Why size matters so much#
Compression only works well when the stocking fits properly. Measure the leg in the morning before swelling has built up. Many products need at least ankle and calf measurements, and some need additional length or thigh measurements.
Use the size chart of the specific manufacturer, because sizing can vary a lot between products.
When the stocking is wrong for the leg#
If the foot becomes cold, pale, blue, numb, or painful, the stocking may be too tight or the fit may be wrong. A stocking should feel snug, but it should not create worrying symptoms.
When to seek care#
Seek care if one leg suddenly swells more than the other, if the leg becomes hot, red, or very painful, if the foot turns cold or pale, or if there is an open wound or clear infection. Review is also sensible if you have known artery disease or are unsure whether compression is safe for you.
