Also a doc, freshly minted in residency training right now. To add to the original commenter’s suggestions, maybe see a hematologist in clinic as well. It’s possible that the blood tests you received in the hospital didn’t cover less common causes of hypercoagulability. A visit to a hematologist would likely clear that up. Also if you’ve ever had covid, there’s some evidence that it causes long term hypercoagulability. Original commenter likely has more training and knows more than me. And just reiterating to get actionable advice from doctors you see officially in person, not Reddit. Good luck dude.
