Lymphoedema and long distance air travel

I have lymphoedema and have travelled long distance (Europe) several times since being diagnosed, with no problems.  Do you actually have lymphoedema or are you just worried about it starting? Unless you have existing damage to your lymphatic system I am not aware of any reason why it would start, but best to discuss with your GP. If you have lymphoedema, or have been told you are at risk, you would be advised not to fly any reasonable distance without a compression garment. A qualified lymphoedema therapist can measure and advise.  You should also do everything possible to move and exercise the affected area during the flight - there are exercises you can do in your seat for arms or legs, but an aisle seat will make it easier to get up, walk around and exercise as often as possible without disturbing others. Moving around is recommended for anyone anyway to avoid deep vein thrombosis. Unfortunately I can't sleep on flights at all, but falling asleep from beginning to end doesn't help at all from a risk reduction point of view, which makes me feel a bit better!  You can also look at the option of breaking your flights with a stopover somewhere en route. Best wishes.
