I've been away for work this week and it has involved walking up a moderate hill each day to get back to the hotel. I've been desk bound for 8-9 hours a day with no real breaks other than to get a drink or go to the toilet. My ankles were very swollen Wednesday and Thursday afternoon/evenings. I slept with my legs up on pillows and they'd go down by morning but swell up again over the course of the day. The last couple of days I've noticed a tenderness in my right calf, today it's gradually gotten worse and is now painful to touch, I had to drive 200 miles home today which hasn't helped. Both of my legs are swollen from the knee down, but if anything the left is worse rather than the right. When I point my toes up it feels like a stretched muscle or the feeling you get after you've had a bad cramp. I did have a bit of a cramp earlier in the week and can be prone to them at the best of times. So have I just had cramp overnight and am feeling the effects of that and walking uphill with a heavy backpack or is this DVT? I also flew back from Portugal nine days ago.
