pulmonary embolism
"Had dvt in which I was prescribed warfarin for.  The constant blood tests were a nightmare as I am extremely hard to get blood from, sometimes taking more than 10 tries. The bruising from the thinners and punctures from blood tests,  I was a bruised mess. Had a PE a year later in January 2015 after being taken off warfarin that almost killed me. I was devastated to think I will  have to take warfarin for the rest of my life. The pharmacist in the hospital told me about xarelto and I was so happy. They proceeded to put me on xarelto. I am experiencing occasional headaches /migraines and I get extremely faint/dizzy while standing up. A small price to pay to be able to eat whatever I want and no constant painful blood drawing every few weeks!"
