Well I went to the pulmonlogist today.... He said with a clot that small in my lungs I shouldnt be having ANY problems.  He also said that the filling defect in my right atrium may be causing the problems.  He thinks this may be a blood clot there...  i go for a CT scan in 30 minutes and a echogram on Friday at 1pm.  I go back to the pulmonologist in a week to discuss the results and if all is good then I get OFF lovenox!!!! Man am I ready!!  The blood clot in the right atrium really scares me!!
