I had my INR check today and thought it would be low, around 3.4ish as I felt very tired. I didn't have any other APS problems though, but felt sure it was low. The actual reading was 5.9! I remember that before when it was over 5 I felt the same, tired but no other symptoms. I was told that maybe I have a virus that has pushed up the INR and made me feel tired, which I guess is possible, but I wondered if anyone else has had this too?
If the INR had been 4.5, I would probably have felt really good, but does the excessive INR cause problems (other than potential bleeds)?
