Something wrong with my hand

Its my left hand it feels like its falling asleep (I don't know the proper medical term for it). That numbing pin and needles fuzzy feeling. its been like that for over three or four days. Yes I had body parts (Hands, feet, legs) fell asleep on me and to an extent to where it hurts but it would eventually went away and I feel normal again.
But this numbing feeling won't go away.
It doesn't hurt and it doesn't really bother with my activities, like typing. I'm using both hands to type but my left pinky and left ring finger feels numb.
I'm just a little worried that this feeling is consistent but its probably nothing
