When travelers should not wait
One-sided leg swelling or calf pain after a long flight or long drive can need DVT ultrasound. If symptoms include chest pain, shortness of breath, fainting, coughing blood, or severe illness, emergency care should come first.
How to prepare the WhatsApp message
Send which leg is affected, when travel happened, flight or drive duration, swelling or pain duration, pregnancy status if relevant, surgery history, cancer history, previous DVT, and any blood-thinner medication.
