Ive been having constant numbness in my left hand. It is mostly my pinky n ring finger.?

It is called ulnar nerve entrapment. Carpal tunnel syndrome affects the rest of the hand. Your ulnar nerve travels through your elbow and gets trapped sometimes causing your little finger and part of your ring finger to go numb. You need to see a doctor because sometimes surgery is required to release it. Other times you can use elbow splints when you sleep. It either gets trapped at the elbow or at the wrist. Do a search for ulnar nerve entrapment because I had the same symptoms and that is what I found.
