Ow Blue, sorry to hear :O must have hurt a lot
But it's healing now, you don't need to do much. And don't worry about
infection as they cared about
your wound in ER, I mean there is no reason for it to get infection if you take care of it before sutures are out.
I have very unpleasant stitch memories from the deep cut I had in my right palm when I was 10 yr old.
Though the 6 months of disability forced me to learn to use my left hand :D
Get well soon !
