Sorry I didn't see this sooner. I have a good friend of mine on Coumadin and she is a LE Ranger. But it may not be easy for you. She already had her job when she got the clot. She was out for a while and when she came back she really had to fight to keep her job. It worked out (thank goodness) and she's a great ranger. She wouldn't want to do anything else.
In life's small things be resolute and great
To keep thy muscle trained: know'st thou when Fate
Thy measure takes, or when she'll say to thee,
"I find thee worthy; do this deed for me?"
Nemo me impune lacessit.
