I had a DVT several months ago--non-occlusive and hardly symptomatic at the time. Now, four months later, the leg pain has returned, but much worse. Two Doppler ultrasounds reveal no new dvt, and no trace of the original clot. My doctors say not to worry, it is just post-dvt pain, but I don't buy it--wouldn't the pain have been worst during the time of the DVT, then steadily improving? It feels just like the original DVT pain, but worse. Any ideas? Any chance two ultrasounds could miss a new clot? Have been on anticoagulants for four months, well controlled...
