I saw several posts that people feel dizzy, fatigue and just plain off when their INR levels are low or high. I told my wife a few days ago I was very fatigued and dizzy and I said I bet my INR level was of, two days later went to GP it was 1.3. I have been diagnosed with APS not sure if this is the same as Hughes Syndrome. Anyway my GP said I shouldn't be able to feel when INR is low but this is the second time this has happened. My GP also insist my INR level be between 2 and 3 I have heard it should be higher, he is very reluctant to refer me to a rheumatologist. Please I need help with information that will back up my thoughts that my INR level should be higher. Thank you for any help it will be much appreciated.
