On January 5th of this year I was diagnosed with a pulmonary embolis. I was quickly admitted to hospital and treated with I M Heparin, one shot upon admission and then 2/day for the next 6 days when I was put on warfarin. Discharged after nine days and told not to fly home for six weeks. I have been home since Feb. 10th. My question is this: I cough very hard very often at times, also I experience upper chest discomfort (from my breasts to my shoulders) and this makes me anxious. It is worse when I over exert myself. Could you tell me what this could be due to. If this is going to cost me anything, please do not answer me) thank you
