I had a bad fall 3 years ago banging my head on the edge of the open door and resulting in a very bad black eye which spread right down my face onto my neck over the following few days. I'm on Rivaroxaban for AF. My husband did take me to A&E but as it was Christmas day and my family were there from down south I chose to go home rather than sit there for hours waiting to be seen. I had also cut my finger at the same time which wouldn't stop bleeding. The next day another family member persuaded me to call in at a different hospital on the way home and the doctor told me I should have called an ambulance - head injuries on blood thinners can cause internal bleeding. I have never been told to stop taking the medication so this does sound a little odd.
I only have routine blood tests annually.
Lack of public toilets in towns.
