What eases DVT symptoms?

Two questions get mixed up here: how to ease DVT symptoms and how to treat the clot behind them. Readers often hunt for one while reading about the other. This page takes the first.
The answer
my.clevelandclinic.org gives one concrete step: "If your legs feel swollen or heavy, lie in bed with your heels propped up about 5 to 6 inches."
The advice is specific about both the symptom and the position. It addresses swollen or heavy legs, and it gives a height for the heels.
Placing it beside the wider picture
The Cleveland Clinic page on deep vein thrombosis is the source of that line. The Cleveland Clinic guide to venous disease sits under a different title, and comparing the two shows how a narrow comfort step differs from the broader subject of vein conditions.
The follow-up question
Propping up the heels is a step about comfort. It raises the question of when swelling and heaviness call for a clinic visit, a question to bring to your own clinician.
