Go see your doctor ASAP. If it is DVT its nothing to put off. Blood clots could break free from your legs and migrate up to your heart and plug a vein in it. I have it in only one leg, occurred suddenly when I got out of my car and thought I'd pulled a muscle. I've been taking warfarin, too, keeps it in check but it'll never go away. I can walk and bike ride normally, but by the end of the day my lower calf is noticeably swollen. I never used the compression socks.
