pulmonary embolism, recurrent event
"I was 39 years old at my first clot after surgery. I went off Coumadin after a year. Then had a pulmonary embolism and was put back on Coumadin.  My INRs had great fluctuations. I now have my own home Coagucheck and adjust my Coumadin with a Dr's supervision and no clot since. I have had side effects but no clots since then."
