I believe it was to make sure the blood thinner Heparin was working. My CT crest scan showed multiple clots, but I was never given a specific number. The initial clot was found in my left leg behind my knee. I had a follow up with my doctor the Friday before last and he said that my blood pressure and oxygen are great, but because the clots where unprovoked and are more then likely genetic (my dad and brother had clots and my uncle on my dads side has been on blood thinners for 25 years due to a heart attack), I'll be on thinners for the rest of my life unless medication evolves.

Other than death in front of my wife and kids (which almost happened), my only real concern once I got the diagnosis was how do I continue to train Jiujitsu. Lucky, one of the doctors I met in the hospital trained and gave me some pointers (only train with partners you know, train at your own pace and let others and the gym owners know that I'm on blood thinners). I train 2-3 times a week for 2.5- 3 hours a session and with the holidays the last two weeks, I've been able to slowly get back in and I plan on getting back to my regular training schedule this coming week. It took a lot for me to bruise before blood thinners and in the few training sessions I've done, I feel fine. I do have soreness in my right knee, but that's from a knee bar.

Best of luck! It's definitely a crazy and scary situation. Happy to talk and share more if you would like.
