question: They found clots in my lungs, legs and other places in my body which they felt were caused by my birth control. The birth control was stopped and I was started on xarelto. Still having shortness of breath pain on right side intermittently. My primary doctor has only told me to follow up in 6monts. Oh I also have sickle cell. Is there more I should be doing and do they need to check some type of blood levels while I am on xarelto.
