Thanks GermanGuy. I'll look into that.
Asked Jordan about the hand via Inta live. He seemed to say at worst I may have avulsed a tendon or damaged the synovial sheath. That if the pain didn't go away/get better to get it checked out.
The bruising is very light and small. ROM is fine. No pain flexing/extending the hand or digits. It used to hurt washing my hands but now that I've rested a few days it doesn't. Only hurts if I press down with some force on that spot. So I assume it's just something minor that's getting better.
I decided to skip the gym because of my hand + there is a nasty flu going around with a lot of reports in my city. Would rather not have to end up needing to see a doctor over either of those.
Will probably miss a few sessions
