Swollen Feet (Paon Ki Sujan): Salt, Sitting, Heat and Red Flags
Water tablets are not a home remedy. That’s the first correction this Desi Remedies guide has to make, because the most common Pakistani response to swollen feet (paon ki sujan) is a Lasix from the corner pharmacy, and it can hurt a person whose swelling is coming from their heart, kidneys or a clot. Most swollen ankles have an ordinary cause: salt, sitting, heat, pregnancy, or a medicine on your own shelf. Here is how to tell the ordinary from the urgent, what genuinely reduces the puffiness, and the exact signs that need a doctor this week or a hospital tonight.

What swelling actually is
Oedema is fluid that has leaked out of the small blood vessels into the tissue under the skin, and because gravity pulls it to the lowest point it collects at the ankles and the tops of the feet by evening and often drains away overnight while you lie flat. Press a thumb into the shin for 5 seconds. A dent that slowly fills is pitting oedema, the ordinary kind. The question is never “is it swelling”, it’s “why is fluid leaking, and is it both legs or one”.
Both legs, worse by evening, better by morning, no pain: usually salt, sitting, heat, weight, pregnancy or a tablet. One leg, painful, warm, or sudden: a different list. A shorter one. Read it first.
The everyday causes, and what fixes each
Salt
Sodium holds water. A Pakistani plate can easily carry 3 to 4 g of sodium a day (8 to 10 g of salt) once achar, papad, namkeen, packet masala, chutney and a bowl of nihari are counted, against a sensible ceiling of about 2 g sodium, which is 5 g of salt, one level teaspoon, for the whole day. The salt you don’t see does more damage than the salt you add: a tablespoon of achar, two papads and a handful of nimko can be half the day’s allowance. Our guides to packet masala sodium and salt and home BP readings do the counting.
Sitting, standing, travelling
Calf muscles are the pump that returns blood from the legs, and eight hours at a desk, a 14-hour bus to Skardu, a wedding spent standing in heels or a night flight to Jeddah all switch that pump off for long enough that fluid simply pools where it is. This is the commonest cause in office workers. It’s also the easiest to prove. Gone by morning, back by evening: sitting.
Heat
In a 42°C June the body opens blood vessels in the skin to shed heat, and more fluid leaks into the tissue. Ankles swell in hot weather in perfectly healthy people, and it eases when the weather does. Keep drinking; cutting water to reduce swelling is backwards, because a dehydrated body holds sodium harder. How much water you need in the heat gives the numbers.
Pregnancy
Mild ankle swelling in the last 3 months is normal; the womb presses on the veins returning blood from the legs and the body carries more fluid. The rules of thumb work well here (feet up, left-side lying, walking, less salt). What’s never normal is covered in the red flags below, and it’s the one part of this guide that can’t wait until the next check-up.
Medicines
Look at the shelf before you look for a totka. Amlodipine and other “dipine” blood-pressure tablets are famous for puffy ankles, and so are painkillers like ibuprofen and diclofenac taken regularly, steroid tablets, pioglitazone for diabetes, pregabalin and gabapentin for nerve pain, some hormone pills and certain antidepressants, which between them cover a good share of the medicine cabinets in any Pakistani home with a grandparent in it. If the swelling started within a few weeks of a new tablet, that’s the likely cause, and the fix is a conversation with the prescriber about an alternative, not stopping it yourself and not adding a water tablet on top.
Weight, veins and age
Extra weight raises pressure in the leg veins, varicose veins leak, and older skin and vessels simply hold fluid more readily. None of this is dangerous by itself, but it’s the group where the serious causes also cluster, so the checks below matter more, not less.
What actually reduces the puffiness
- Feet above the heart, not on a stool. Lie flat and prop the feet on 2 or 3 pillows so the ankles sit higher than the chest, 20 to 30 minutes, 2 or 3 times a day. A foot stool while sitting does very little; the ankle is still below the heart.
- Pump the calves. Every hour of sitting, 2 minutes of heel raises (20 to 30) or a walk to the kitchen and back. On a long bus or flight, ankle circles every 30 minutes, 10 each way. A 20-minute walk in the evening drains more than any soak.
- Cut the hidden salt for a fortnight. No achar, papad, namkeen, packet soups or processed meat for 14 days, and cook with a measured 1 tsp of salt for the family pot rather than “andaaza”. Most salt-driven swelling shows a difference inside a week.
- Cool, not hot. A 10-minute soak in cool tap water (20 to 25°C), or a cool wet towel over the ankles, tightens vessels a little and feels good. Hot foot soaks and hot water bottles open vessels and make oedema worse.
- Compression socks for standing jobs and travel. Pharmacy compression socks of light to medium pressure, put on first thing in the morning before the swelling builds, off at night. Not for anyone with poor circulation in the legs or diabetic foot problems without a doctor’s say-so.
- Loose shoes and no tight elastic. Socks that leave a deep ring at the calf are a mini-tourniquet. Change them.
The 7-day check
Measure both ankles with a tailor’s tape at the narrowest point every evening for a week, and note salt, sitting hours and heat. Swelling that tracks those three and drops with the steps above is the ordinary kind. Swelling that doesn’t budge in 7 days, is more than 1 cm bigger on one side, or keeps climbing up the leg needs the doctor’s list below. Bring the numbers; they help.
Hakeems treated swelling as excess cold and wet in the body, and the household answer was warming, drying food and a light diet: less salt and pickle, barley (jau) water, roasted jeera, and dry ginger. Ayurvedic practice added elevation and gentle oil massage upward toward the knee. The low-salt, light-food part matches modern advice well; the massage is pleasant and harmless on an ordinary swollen ankle but must never be done on a leg that might have a clot.
The red flags: heart, kidney, liver and clot
Read this section even if you’re sure it’s just the heat. Each cause has a signature. Each is easy to check at home.
The heart
Both legs, plus breathlessness when lying flat so you need extra pillows, waking at night gasping, a cough when you lie down, tiredness on stairs you used to manage, and weight up 2 kg in 3 days with no change in eating. Heart-failure fluid is body-wide fluid. Anyone with high blood pressure, diabetes, a previous heart attack, or over 60, with swelling plus any of those, needs a doctor this week; breathlessness at rest is the same day.
The kidneys
Puffiness around the eyes in the morning, frothy or bubbly urine that lingers in the pan, swelling that’s present on waking rather than only by evening, less urine than usual, and high blood pressure. A urine dipstick for protein and a blood creatinine test are cheap and settle it. Diabetics and anyone with high BP should have both checked yearly anyway.
The liver
Leg swelling with a swollen belly, yellow eyes, easy bruising, or a history of hepatitis B or C. Pakistan has a lot of undiagnosed hepatitis C, and swollen ankles are sometimes the first sign anyone notices.
A clot (DVT)
One leg, usually the calf, swollen, tender, warm and often slightly red, sometimes with a pulling ache when you flex the foot up. The classic set-ups are a long trip, recent surgery, bed rest, pregnancy or the weeks after delivery, the pill, cancer, or a previous clot. A swollen, painful calf on one side is seen the same day, even if you feel otherwise fine. A DVT is an emergency because a piece can break off and travel to the lungs, so one-sided swelling with chest pain, sudden breathlessness or coughing blood means an ambulance rather than an Uber, and a leg that might have a clot is never massaged, squeezed or soaked. Not by you. Not by a maalish-wali.
Other things that get missed
An underactive thyroid causes a doughy, non-pitting swelling with tiredness, dry skin and weight gain; a TSH test finds it. Low protein from poor diet or gut disease causes generalised swelling. A skin infection (cellulitis) gives one hot, red, painful, spreading area, often with fever, and needs antibiotics the same day.
Never take a diuretic (Lasix, furosemide, spironolactone, or “water pills” of any kind) without a doctor; they can drop your potassium or sodium, dehydrate you, harm the kidneys, and they hide the cause. Don’t stop or reduce a blood-pressure, heart or diabetes medicine you suspect of causing swelling; ask the prescriber for a change instead. In pregnancy, sudden swelling of the face or hands, swelling with a headache, blurred vision, pain under the right ribs, or a BP reading of 140/90 or higher is pre-eclampsia until proven otherwise and needs a hospital the same day. Don’t use compression socks over poor leg circulation, ulcers or a suspected clot. Salt substitutes (potassium salts) are not a free swap if you have kidney disease or take spironolactone, ACE inhibitors or ARBs; ask first. Herbal “water-reducing” powders and slimming teas contain undeclared diuretics often enough that they belong in the same warning.
Questions people ask
Why are my feet swollen only in the evening?
Gravity and sitting. Fluid that pooled over a day of sitting or standing drains overnight while you’re flat. That daily rhythm, with both feet equal and no pain, is the reassuring pattern. Fix it with hourly calf pumping, evening elevation and less hidden salt.
Should I drink less water to reduce swelling?
No. Cutting water makes the body hold sodium and fluid harder, and in the heat it puts you at real risk. Drink normally, cut salt instead, and keep the legs moving.
Is swelling in pregnancy dangerous?
Mild ankle swelling in the last trimester is expected. Sudden swelling of the face and hands, a headache, vision changes, pain under the right ribs, or BP at or above 140/90 is not, and needs the same-day check for pre-eclampsia.
My BP tablet causes swollen ankles. Can I stop it?
Not on your own. Ankle swelling from amlodipine-type tablets is common and there are alternatives, but stopping a BP tablet suddenly is riskier than the swelling. Ask the prescriber for a switch.
Does a hot salt-water foot soak help?
It feels good and does nothing for oedema; heat opens the vessels and can make the swelling worse for the evening. Cool water is the better soak. Hot water is also risky for diabetics who may not feel a burn.
Which tests will a doctor order?
Usually a urine test for protein, blood tests for kidney function, liver, thyroid and albumin, sometimes a heart blood test, and, depending on the story, an ECG, an echo of the heart, or a leg ultrasound to rule out a clot. Bring your medicine list; it’s often the answer.
How fast should swelling go down with home steps?
Sitting and heat swelling improves overnight and clearly within 3 to 7 days once you raise the legs, move and cut salt. If nothing has changed after 7 days, or it’s getting worse, stop treating and get it checked.
