Numbness in my pinky, pain in my ring finger. Arthritis?

I do not think so. When you have numbness this means a nerve in that area or above some problem? Check it out. Thank you.
Nerve. Agree with the two prior answers. It's a nerve problem in usually one or more of the following locations: neck, armpit (thoracic outlet), elbow, or wrist. As to arthritis, that could possibly contribute to neck related nerve involvement.
