Pulmonary Embolism Support Group
By far the most common form of pulmonary embolism is a thromboembolism, which occurs when a blood clot, generally a venous thrombus, becomes dislodged from its site of formation and embolizes to the arterial blood supply of one of the lungs. Symptoms may include difficulty breathing, pain during breathing, and more rarely circulatory instability and death.
I'm really glad that you felt relief after talking to your doc and also that you are stepping back a little and examining everything. Also, that you're able to laugh at yourself a little. All steps forward and all good!
as for increasing the dose - my dr does the increases gradually - ie if my inr is 1.6 say he would increase it maybe by 1mg per day but this week it was 1.8 so it was increased by 1mg on alternate days. It means its not jumping drastically all over the place.
