mine swell and invested in scholls flight socks, they make my legs feel great, so far no probs, ( i am very worried about DVT as my mum passed away due to that!) its the only time my legs have anything on them, what about your GP can they advise you?
must say my legs feel really good after each flight, and as most know i have the baddie knee,apart from the pain in my knee, and as the socks dont cover them i at least know that my legs will feel fine....
