It's a carpal tunnel owie. You'll be fine.
Just for fun I was doing hammer cursl at the end of my session and when gripping the dumbbell somewhat harder I feel a jolt like an electric shock going from the middle of my forearm (line towards my thumb) straight up to my thumb. Feels like a tendon "jumping" around. Not really painful but very uncomfortable. Only on my left side. Im right handed. What could this be? De Quervain's probably not bc I don't have any of the other symtoms as far as I see.

Ok. So just ignore that stuff and continue?
Treating the thing itself of course. I don't mind the uncofortable feeling just don't want to injure anything.
If you're afraid of the thing, get it looked at.
