<s>[INST] In January my husband was diagnosed with a d.v.t. In his left calf. He is now on daily warfarin. We had already booked a holiday in March which will need a 4 hour flight our G.P said its O.K to go. Does my husband need to wear compression stockings on both legs [/INST] Yes, compression stockings are helpful to push blood in upper part and prevent recurrence of your disease. So my advice is to your husband- he should wear them all the time when he is either sitting, lying or standing. Also he should keep on moving ankle if he is awake. Avoid high fatty diet, try to loose weight also. </s>
