My father just came to our place from Dominican 4 hour flight, both his legs from his knees down are quite swollen, how do we get his swelling down. He is 66 and had a heart attack 4 months ago.

You had better get your father checked out by a doctor. What type of medications is he taking. What type of medical conditions does he have?

Tick

You may want to keep is legs elevated and contact a doctor for further advice

No,don't keep his legs elevated!

On the off chance he may have a clot this is not a good position.

Just have him sit down and call a doctor.

Please do NOT keep the legs elevated and seek medical attention at once. This may be a DVT (Deep Vein Thrombosis), a blood clot, that could dislodge and go to the lungs almost instantly killing him if it should break free when the legs are elevated.

Seek medical attention NOW.
