A member asked:

How long does it take for new blood clots to form? doppler scan showed clear of leg clots 6 months ago. worried that they might be coming back already

A doctor has provided 1 answer

Any time: New clots can form at any time. If someone has had blood clots in the legs before, it is common for the legs to swell and be painful even if no new clots have formed. If leg pain or swelling returns, it is best to see a health care provider to determine what is happening.
