I am presently taking Coumdin and have three issues that concern me deeply. Does Rivaroxaban overcome of these issues?

1. Need to have frequent blood analysis of my level

2. If unbeknown to me should my blood level be to high I am place in a dangerous position from bleeding especially if I should have an accident that might cause some internal bleeding.

3. Should I be placed in a position where I have an immediate need to have surgery present a serious problem
