Scar ripped open?

So
1

A month ago I tore my finger exactly at the bend between the metacarpal bone and the first phalanx… It only healed slowly and there was a scar right there that made it impossible for me to bend my finger properly. I just slept on the table after a FIFA goal and it was stupidly exactly the increase in the scar on the laptop and completely torn open. So the fresh scar is completely torn open, it bleeds, the finger hurts and I can hardly move it…

What can I do?

Ja

Off to the doctor, not that something ignites. Otherwise disinfect and connect yourself with aniseptic.
