For About Two Weeks I Have Felt Numbness And Tingling

For about two weeks I have felt numbness and tingling in my left little finger and some in the left ring finger (ulnar distribution). Yesterday I realized I had weakness in the left hand when I was unable to clip my right hand finger nails and I had a little trouble removing a cork from a bottle with my left hand. So, weakness in my left hand finger grip and ulnar numbness/paresthesia of a couple weeks duration.
