I'm on rivaroxaban following a second bout of PEs. I have high blood pressure well controlled by lisinopril. The first PE in March 2017 was thrombolysed as it was massive. I was then on warfarin for 6 months and came off that in October. On 21st Dec I went to the doctor because I was breathless again. The D-dimer blood test was 3200-ish (I know the cutoff for D-dimer is 500, increasing with age - so was that very high?). He sent me to ambulatory care at the local hospital. CT scan showed lots of embolisms on both sides of the lungs, top, middle and bottom, so now I am on anti-clogs for life - which I don't mind as I prefer drugs over slow suffocation! What I am curious about is, what are these random sensations - like being poked from the inside - that I'm now feeling in chest and back and sometimes in my muscles? Could these be clots breaking up? They are not painful, just noticeable. Since the first PE was thrombolysed, I have no experience to compare.
