Tracy,

I do not know exactly what happened to you, but if you had pain in your calves and associated difficulty in breathing your doctors must think of pulmonary embolism. it seems that you had a fleeting attack of that and not a massive one. I suggest you take 75 mg of aspirin per day to keep your blood thin and to prevent clotting. Please go back to your doctors and explain that and ask them to take matters a bit more seriously than the casuality doctors did.

I wish you better.

best wishes.
