I have a unit, similar to a glucose monitor, that I check my INR with every ten days. It has helped me keep an eye on dosage, as I enter the result on a site provided by Roche, the Makers of the INR meter. They notify my doctor of any changes needed & he calls me with a new dosage.
What you described sounded like an arterial bleed. Did you cut yourself on the frame of the bed? A venous bleed is much different. Was the blood bright red or dark? I believe I would be sleeping, or trying to sleep, with that leg elevated for a while.
A friend of mine took thinners for years.Whenever he nicked himself shaving he would holler-Mary,I'm gonna bleed out! [emoji33]
I miss hunting and fishing with that goof !
