About half of people with DVT have no symptoms until a clot blocks a major vein. Because the symptoms can be caused by other conditions, tests are needed to confirm the diagnosis. Heparin is injected into a vein while you are hospitalized. Leg compression devices are often used to prevent DVT while you are in the hospital. You will have blood tests from time to time to check how well the drugs are working.
Some people have a tendency to form blood clots more easily than others.
They may have DVT frequently and may have to take anticoagulants for the rest of their lives. Wear special elastic stockings. Take them off once a day to allow the skin to be cleaned and inspected for discoloration or irritation. You should have at least two pairs of the stockings to allow for washing and drying each day. Stocking lengths vary from those that extend to the knee to those that cover the thigh.
