How long does it take for deep vein thrombosis to go, is it normal for the swelling to get worse? Thankyou

Can take a long time. Sometimes clots never disappear. If the clot is not gone in 6 months, it is considered to be permanent. Swelling can get worse, especially if you develop post thrombotic syndrome (pts). A dr. Vichen said, you need to be on anti-coagulation. Also wearing prescription compression stockings for two years is essential in helping to prevent pts from occurring.
A week wittreatment . Hoping you have started on anticoagulation and you have therapeutic range, keeping your leg vested, usually within a week the swelling should go away. You need to be maintained on anticoagulants for 6 months., keep monitoring your anticoagulant parameter.
Yes increased. Swelling possible...It can take 6-12 weeks with appropriate anticoagulant ion.
