Given that blood clot formation varies in people, the best thing to do to stay safe is look out for the symptoms.
However, symptoms may not come on all at once, as when a clot in the veins carries blood back to your heart, signs can come through more gradually – but this could still be trouble.
As soon as you start noticing any of these symptoms, get help as soon as possible because DVTs can travel to your heart of lungs, worsening the situation.
DVTs are more likely to occur in people who haven’t moved around for a long time, for example after a surgery or during a long journey.
