Paon Ki Sujan: Causes and Red Flags
One swollen foot and two swollen feet are different problems, and the difference decides whether you put your feet up tonight or get to a hospital. This guide ranks the causes of paon ki sujan by what to rule out first, not by what is most common.
The short version
- One foot or leg, sudden, painful, warm: possible clot or infection, same-day care
- Both feet with breathlessness: think heart, get seen that day
- Both feet with puffy face or foamy urine: think kidney, get tested this week
- Both feet, worse by evening, gone by morning, no other symptoms: usually ordinary, see the home care guide
- In pregnancy, with headache or blurred vision: same-day emergency

Start with three questions
Before any remedy, sort the swelling. It takes two minutes and needs no equipment.
One side or both?
Both ankles puffing up together points to something affecting the whole body: fluid balance, salt, hormones, a tablet, gravity. One leg alone points to something local, in that leg’s veins, skin or joints. Local is where clots and infections live, and they do not wait.
Sudden or gradual?
Swelling that builds over weeks, worse in the evening, is a slow story. Swelling that appears over hours or a day, especially after a long flight, a hospital stay, surgery or weeks in bed, is a fast one. Fast plus one-sided is the combination to fear.
Does it pit?
Press a thumb firmly into the shin or the top of the foot for 5 seconds, then lift it. A dent that stays and slowly fills back is pitting oedema, meaning fluid in the tissue. Swelling that springs straight back and feels firm or rubbery is a different tissue problem, and thyroid disease and lymph blockage are two examples. Either answer is worth telling a doctor.
- Sit with both legs level with each other and compare ankle bones. Is one side clearly fatter?
- Press a thumb into each shin for 5 seconds. Note the dent depth and how long it takes to fill.
- Check the skin: any redness, warmth, shine or tenderness along the calf?
- Look at your face in the mirror and at your urine. Puffy eyelids at wake-up or foam that stays for more than a minute after flushing are worth reporting.
- Note breathlessness lying flat or needing extra pillows.
- Weigh yourself each morning for 3 days. A gain of more than 2 kg over 3 days, with no change in eating, suggests fluid, not fat.
The red-flag patterns, in order of urgency
Read this list top down. The first items need care today, and the later ones need an appointment.
| Pattern | Likely direction | What to do that day |
|---|---|---|
| One leg, sudden, calf pain, warm | Deep vein clot | Emergency department, do not massage |
| One leg, red, hot, fever | Skin infection (cellulitis) | Doctor same day |
| Both feet plus breathlessness | Heart or lung | Urgent review, hospital if severe |
| Both feet plus puffy face, foamy urine | Kidney | Doctor this week, urine and blood tests |
| Both feet plus yellow eyes, big belly | Liver | Doctor within a day or two |
| Pregnant, sudden swelling, headache | Pre-eclampsia | Maternity unit now |
| Both feet, evening only, no symptoms | Salt, sitting, heat, medicine | Home measures, review if it persists |
One foot: clot or infection
A deep vein thrombosis is a clot in a leg vein. It usually gives a swollen, achy, warm calf on one side, sometimes with a heavy tightness when you flex the foot upward. Risk rises after long travel, surgery, childbirth, immobility, cancer, and with oestrogen pills. The danger is a piece breaking off and lodging in the lung, so sudden breathlessness, chest pain or coughing blood with a swollen leg is an emergency, and you should not walk it off.
Cellulitis is a bacterial skin infection: a red, hot, tight, tender patch that spreads, often with a fever and a chill. People with diabetes, cracked heels or fungal infection between the toes are prone. It needs antibiotics from a doctor, and it can spread fast.
Other one-sided causes are an injury, a gout attack in the big toe or ankle, a ruptured cyst behind the knee, and a long-standing vein problem. A doctor sorts these by examination and sometimes an ultrasound.
Both feet, with breathlessness: the heart question
When the heart pumps weakly, fluid backs up, and ankles swell along with getting breathless on the stairs, waking at night short of breath, needing more pillows, or tiring on walks that used to be easy. Weight climbing quickly is another sign. This is not a home-remedy zone. A physical exam, an ECG, blood tests and often an echocardiogram are the route. Lung disease that strains the right side of the heart gives a similar picture, especially in long-term smokers.
Both feet, with a puffy face or foamy urine: the kidney question
Kidneys that leak protein or fail to remove salt let fluid pool. The clue is swelling around the eyes on waking, then the feet later in the day, plus urine that foams and stays foamy. People with long-standing diabetes or high blood pressure are the ones to worry about. A urine test for protein and a blood test for creatinine are cheap and settle the question. Also see our guide on salt, food and blood pressure, because the same habits harm both.
Both feet, with jaundice or a swollen belly: the liver question
Advanced liver disease lowers a blood protein that holds fluid in the vessels, so water seeps out into the legs and the abdomen. A tight, growing belly with yellow eyes, dark urine, easy bruising or vomiting blood needs same-day medical care. Do not wait to see if it settles.
Pregnancy: the one that cannot wait
Mild ankle swelling in the third trimester is common. Swelling in one leg only, with calf pain, is different, since pregnancy raises clot risk, so treat it as a possible clot. What separates it from pre-eclampsia is the company it keeps. Blood pressure at or above 140/90 on two readings, a severe headache that painkillers do not shift, flashing lights or blurred vision, pain under the right ribs, and sudden swelling of the face and hands, all mean a maternity unit within hours, not an appointment next week. A reading of 160/110 is an emergency by itself. If you are pregnant and unsure, phone your clinic. It is always acceptable to ask.
Do not buy a water tablet from a pharmacy counter to shrink swollen feet. If the swelling comes from the heart, kidneys or liver, it can drop blood pressure, upset your salts and hide the real problem. Do not massage a hot, painful calf, since a clot may dislodge. Do not stop a regular medicine on your own because you suspect it, and equally do not keep taking something you think is causing harm without asking. Tell the prescriber, and let them adjust it. Go to emergency care for swelling with chest pain, sudden breathlessness, confusion, fainting, or a leg that is white, blue or cold.
The medicine on your own shelf
A surprising number of ankle swellings start with a tablet. The usual suspects are amlodipine and related blood-pressure medicines, regular anti-inflammatory painkillers such as ibuprofen and diclofenac, steroid tablets, pioglitazone and similar diabetes tablets, pregabalin and gabapentin, and some hormone preparations. The rule is the same for all of them: ask, do not stop. The prescriber may change the dose, swap the medicine or confirm it is safe to carry on. Stopping blood-pressure or diabetes medicine on your own can cause far more harm than swollen ankles. Bring the strip or the box to the appointment.
The quieter causes
Thyroid
An underactive thyroid can give a firm, non-pitting puffiness, with tiredness, dry skin, feeling cold and constipation. A TSH blood test answers it. Our piece on thyroid, weight and levothyroxine covers the medicine side.
Long sitting and standing
Calf muscles pump blood upward, and eight hours at a desk switches the pump off. The swelling is symmetrical, painless, and gone by morning. Standing up every 30 to 60 minutes and 20 calf raises are the sensible countermeasures.
Veins, salt and heat
Weak leg veins, a heavy salt day and 42°C weather each add fluid at the ankle. They are ordinary and common, though they can hide a bigger problem if the swelling is worsening month on month.
Grandmothers reached for a warm salt-water foot soak and a firm crepe bandage, and told you to sleep with the feet on a pillow. The soak feels good and the elevation is genuinely sensible. Neither answers the question of why the swelling exists, which is the point of this page.
When to book an ordinary appointment
Swelling that does not clear overnight for more than 2 weeks, keeps returning, or is slowly getting worse deserves a review with blood pressure, urine, kidney, liver and thyroid checks. Bring the medicine list, a note of how many pillows you sleep on, and your morning weights.
Questions people ask
When is swelling in the feet serious?
Get care the same day if one leg swells suddenly with pain or warmth, if swelling comes with breathlessness or fever, if yellow eyes or a growing belly appear, or if you’re pregnant with a headache or blurred vision. Chest pain, fainting, confusion or a leg that turns white, blue or cold means emergency care now. Evening swelling in both feet that’s gone by morning is usually ordinary.
Which is more dangerous, one swollen leg or two?
One swollen leg with pain or warmth is more likely to be a clot or infection and needs faster attention. Two swollen legs point to a body-wide cause, and how urgent it is depends on the symptoms that come with it.
Is swelling in both feet in the evening always harmless?
Usually, if it’s gone by morning and nothing else is wrong. If it now leaves a lasting dent, is climbing towards the knees, or comes with breathlessness or puffy eyes, it needs checking.
How do I know if a swollen leg is a blood clot?
A clot usually gives one swollen, achy, warm calf, sometimes tight when you pull the foot upward, often after travel, surgery, childbirth or bed rest. You can’t confirm it at home. Go to emergency care, and don’t massage the leg.
Can heart problems cause swollen feet?
They can. A weak heart lets fluid back up, so ankles swell along with breathlessness on stairs, waking up short of breath or needing more pillows. That needs a doctor promptly, not a home remedy.
Can kidney problems cause swelling in the feet?
Yes. The typical clue is puffy eyes on waking, feet swelling later in the day and urine that foams and stays foamy. A cheap urine test for protein and a blood test for creatinine answer the question, especially if you have diabetes or high BP.
Can amlodipine really swell my ankles?
It’s a well-known side effect. Don’t stop it yourself. Tell the prescriber, who can change the dose or switch you to something that suits you better.
Which medicines cause swelling in the feet?
Common culprits are amlodipine and related BP tablets, regular ibuprofen or diclofenac, steroid tablets, pioglitazone, pregabalin and gabapentin, and some hormone preparations. Take the strip to your doctor rather than stopping anything on your own.
Is swelling normal during pregnancy?
Mild, even ankle swelling late in pregnancy is common. Sudden swelling of the face and hands, one swollen leg with calf pain, or any swelling with headache, vision changes or BP at or above 140/90 needs the maternity unit within hours.
Can I take a water tablet for swollen feet?
Don’t buy one over the counter for this. If the swelling comes from the heart, kidneys or liver, a water tablet can drop your blood pressure, upset your salts and hide the real cause. A doctor needs to decide.
How can I tell if my swelling is pitting?
Press your thumb firmly into the shin or top of the foot for 5 seconds. If a dent stays and slowly fills back, that’s pitting oedema, meaning fluid in the tissue. Firm swelling that springs back points elsewhere, such as the thyroid or lymph.
Can thyroid cause swollen feet?
An underactive thyroid can cause a firm, non-pitting puffiness along with tiredness, dry skin, feeling cold and qabz. A TSH blood test sorts it out.
How long can I sit before swelling becomes a clot risk?
There’s no exact cut-off, but trips of more than roughly 4 hours raise the risk. Walk the aisle every hour or two, flex your ankles often and keep drinking water.
Do compression socks help swollen feet?
They can ease ordinary evening swelling from standing or weak veins. Check with a doctor first if you have poor circulation, numb feet or diabetes, because the wrong pressure can do harm.
When should I book a routine check for swollen feet?
Book one if the swelling hasn’t cleared overnight for more than 2 weeks, keeps coming back or is slowly getting worse. Bring your medicine list, your morning weights and a note of how many pillows you sleep on.
