Common Symptoms
Puffy ankles and feet are one of the commonest complaints of visitors and residents in Spain, especially in summer and after a long flight or drive. Most cases are harmless fluid pooling; a few signal a clot, an infection or a heart problem. You may notice:
- Both feet and ankles swollen by the end of the day, better after a night in bed
- Swelling that started on a long flight or after hours of sitting or standing
- Tight shoes, sock marks or shiny, stretched skin over the ankles
- Swelling that leaves a dent when you press it (pitting)
- Heavy, aching legs in hot weather or after walking a lot
- Swelling that began after starting a new medicine, such as a blood-pressure tablet
- One ankle or calf that is more swollen, warm or painful than the other
Swollen ankles on holiday are usually a nuisance rather than a danger, but it is reasonable to worry about a blood clot after a flight or about your heart. A short video consultation can usually settle which it is and tell you whether you need a scan or a blood test the same day.

How We Treat It
The doctor will ask how the swelling started, whether it affects one or both legs, about travel, medicines, pregnancy and heart or kidney history, and will look at your legs on camera. Depending on the cause, care may include:
- Simple measures for heat and travel swelling: raising the legs above hip level, walking and calf exercises, cool showers, limiting salt and avoiding long periods standing still
- Graduated compression socks or stockings for travel and venous swelling, once poor arterial circulation has been excluded
- A review of medicines that cause ankle swelling, such as amlodipine and other calcium-channel blockers, anti-inflammatories, steroids and some diabetes drugs, with a plan agreed with your prescriber
- Same-day referral for an ultrasound scan when a deep vein thrombosis is possible, and advice on where to have it done in Spain
- Treatment of a skin infection (cellulitis) with antibiotics when clinically indicated
- Advice on tests for heart, kidney, liver or thyroid causes when both legs swell with other symptoms
Diuretics (water tablets) are not a treatment for ordinary gravity or heat swelling and can cause dehydration and low blood pressure in hot weather; they are used only for specific medical causes. For flights, the evidence supports moving, drinking water and compression stockings; aspirin is not recommended to prevent travel clots.
Clinical Evaluation & Evidence-Based Protocol for Swollen Ankles and Feet: Heat, Flying, Causes and When to See a Doctor
During a telemedicine consultation with Dr. Pedro Yelamo Vera (licensed medical practitioner No. 484814280 at the Official Medical College of Bizkaia), clinical evaluation adheres strictly to evidence-based medical (EBM) standards. The doctor conducts a thorough history, evaluating symptom duration, aggravating factors, prior treatments, and drug allergies to establish an accurate differential diagnosis.
Private Electronic Prescriptions (Receta Médica) Issued Under Spanish Law
When clinically indicated, Dr. Yelamo issues a private electronic prescription (Receta Médica Electrónica Privada) under Spanish law. The digital prescription contains a secure QR verification code accepted at all 22,000+ registered community pharmacies across Spain for immediate medication dispensing.
Itemized Invoices for Travel & Private Health Insurance Reimbursement
After your consultation, you receive an official medical report and an itemized invoice. The invoice shows Dr. Yelamo's licence details and tax ID. You can send it to your travel or private health insurer (such as Bupa, Allianz, Cigna, AXA or a US travel policy) to claim the cost back.
Preparing for Your Online Medical Consultation
Before your appointment, note when your symptoms started and any medicines you have already tried. Have your allergies and your usual prescriptions to hand. For a skin, rash or eye problem, sit in a well-lit room so the doctor can see it clearly.
Clinical Follow-Up & When In-Person Urgencias Are Necessary
Video care works well for common infections, mild sudden symptoms, skin rashes and repeat prescriptions. Some warning signs need emergency care in person: severe shortness of breath, a high fever you cannot bring down, chest pain or a stiff neck. If you have any of them, call 112 in Spain straight away.
When to Seek Immediate In-Person Care
Seek urgent in-person care (urgencias or 112) if you have:
- Swelling, pain, warmth or redness in one calf or thigh, especially after a flight, surgery or a period of immobility (possible deep vein thrombosis)
- Sudden breathlessness, chest pain or coughing up blood (possible pulmonary embolism: call 112)
- Swelling with spreading redness, heat, severe pain or fever (possible cellulitis)
- Breathlessness lying flat, waking at night short of breath, or rapid weight gain with swelling (possible heart failure)
- Swelling in pregnancy with headache, visual disturbance, upper abdominal pain or high blood pressure
- Swelling after an injury with severe pain or inability to put weight on the foot
Frequently asked questions
Why do my ankles swell in the heat in Spain?
In hot weather the blood vessels in the legs widen to lose heat, and more fluid leaks into the tissues; gravity then pulls it to the ankles and feet, especially if you sit or stand for long periods. It affects both legs, is worse in the evening and improves overnight. Cooling the legs, raising them, walking and limiting salt usually help within days. If only one leg swells, or there is pain, redness or breathlessness, it needs assessment.
Is it normal for ankles to swell after flying?
Mild swelling of both ankles after a flight of a few hours is common and comes from sitting still with the legs down. It should settle within a day or two of walking and resting with the legs up. Swelling that affects one leg, is painful, or comes with calf tenderness or breathlessness could be a deep vein thrombosis and must be assessed urgently, ideally with an ultrasound scan the same day.
Which medicines cause swollen ankles?
The commonest culprit is amlodipine and the other calcium-channel blockers used for blood pressure; ibuprofen and other anti-inflammatories, corticosteroids, some diabetes tablets such as pioglitazone, hormone treatments and some antidepressants can also cause it. Do not stop a prescribed medicine on your own: the doctor can confirm whether the drug is responsible and discuss alternatives with you or your usual prescriber.
How do I know if the swelling is my heart?
Heart failure usually causes swelling in both legs that builds up over days or weeks, together with breathlessness on exertion or when lying flat, waking at night short of breath, tiredness and weight gain. Swelling of both ankles alone, with none of those symptoms, in hot weather or after travel is rarely due to the heart. The doctor may arrange a blood test and an echocardiogram if the pattern is suspicious.
Can I prevent swollen ankles on long flights?
Choose an aisle seat if you can, walk every hour, do calf raises and ankle circles while seated, drink water, avoid alcohol and sleeping tablets, and wear below-knee graduated compression socks (15 to 30 mmHg), which reduce both swelling and the risk of a clot. If you have had a previous clot, recent surgery, cancer or are pregnant, ask the doctor before you travel: you may need specific prevention.
What can an online doctor do for swollen ankles?
Look at your legs on camera, ask the questions that separate harmless swelling from a clot, infection or heart problem, review your medicines, and start simple treatment. If a scan or blood test is needed, the doctor will tell you exactly which test, how urgently and where to get it in Spain, and can issue a referral letter. Suspected pulmonary embolism or severe breathlessness is always a 112 call, not a video consultation.
Online consultations are for urgent, non-emergency care. In a medical emergency call 112 immediately or go to your nearest emergency department.
