Hi Dr.,I have a DVT and have recently needed to stay off coumadin for 6 days in order to get a spinal epidural (recovering from herniated disc-the immobility caused the DVT). I have been on coumadin for just over 6 months now, and wondering if I should be concerned about a PE while I wait for my INR to get within therapeutic range again? I ve noticed since being off coumadin my chest has felt slightly heavier, I ve had an infrequent dry cough and also burping (air mostly, not belching) all the time. Any suggestions here would be appreciated! Thanks!
