Hello, I took a long haul flight of 14 hours, 5 days back to visit India from Europe. I developed swelling in my feet on flight which later progressed into swelling of my legs, hand and face after landing. It has been 5 days since my flight but the swelling hasn't gone down and is now causing discomfort and sensitivity. I do know this is edema but I was of the knowledge that it goes down on its own in a few hours. I've kept my legs lifted over my heart, sufficient water intake. What else can I do to get rid of this? I return to Europe in one week, thanks in advance!
