And if so, what anticoagulant do you take?
A couple of months after I started taking warfarin I noticed a painful blue spot on the middle of one finger. It was hot and angry and soon spread into a purple bruise. Next day it was bigger and had spread but wasn't as painful and had cooled down. It spread out and disappeared after a couple of days.
I had two more and went to A and E with the third which didn't move me forwards, just took up a whole Saturday morning. I had been anxious that these weren't cropping up elsewhere, like my brain.
Have had a fourth one recently and searching online tells me these are Achenbach's syndrome. Happily, it is a finger and toe thing. I don't think it is necessarily connected with warfarin.
