I have also had a deep vein thrombosis when I was 35, and it was located in my right bicep. My doctor ran a litany of blood tests, and it was found I have Factor V Lieden, which basically your blood doesn't know how to stop clotting and you are at a 7 times higher risk for deep vein blood clots than everyone else. I had to do the Lovenox shots for 10 days also, and I am on blood thinners for life because of my diagnosis.

Since then I have also been diagnosed with hypothyroidism and PN...I am falling apart at a young age lol.
