Pulling in the hand

I Have a pulling like feeling in my hand and wrist when I use it certain ways and my thumb and forefinger has some numbness to them. I do remember a while back when I went to pull my car door shut, I twisted my hand and it hurt for a few minutes and was fine. Just was wondering if this could have caused that. I do not have much pain in my hand or fingers, every once in a while I will get a ache in my thumb or wrist but only lasts a second. More concerned with the slight numbness in my thumb and forefinger. I did go to my doctor and he gave me a cortisone shot in the wrist, he said he may help and it may not help which it did not. Just wondered if anyone else is experiencing this. Thank you.
