I had a DVT almost six months ago and went on a 3 month course of warfarin. Which seemed to work as the pain and swelling went. However just over a week ago I started limping again and had pain in my calf again the same place as before. I have been feeling pretty rough last couple of days feeling tired and light headed with tight chest pains and nearly fainted a couple of times. Felt really bad last night so took a trip to A and E . I had quite a few tests done ECG, oxygen levels in my blood and a chest X-ray . But they didn't show anything and results were normal. Doc said it must be a muscle complaint causing my chest pain. He also done a D Dimer blood test which did come back high, and as I have a history of blood clots he has put me in for an ultra sound on my leg which I'm still waiting for. I still feel pretty crappy today and still have a tight chest which is painful at times and generally feel nackered and worn out. Ive heard of PE but don't really know anything about it as last time I had a clot I didn't feel like this. Any advice would be appreciated. Thanks.
