I have been on Xarelto since switching from Cumadin a month ago and about a week ago I had sharp pains in my chest then three days ago I had an irregular fast heartbeat on the lower right side of my heart for about 30 minutes. Once that was over I had wheezing in my chest for the next 12 hrs with severe fatigue and was very exhausted feeling lots of pain in my chest. I was wondering if anyone has had a blood clot while on xarelto. I am having lots of tests done to diagnose what happened, but I believe it was another blood clot due to my symptoms
