It is a long story but I was taken off the flying roster for 3 weeks while my INR was stabilized. I then went on a 10 day trip during which I became quite fatigued as well. Other symptoms started showing after about a week and when I went home, I drove straight to a hospital for a blood test. My INR target was 3.0 and my actual was 13.3. I had also developed a large GI bleed. I collapsed shortly after having the test and had lost about 60% of my blood.

5 days and 17 units of plasma later, I was discharged but felt horrible for 6 months.

Watch for internal bleeding, It is quite obvious!
