Ulnar nerve compression at the wrist: This causes numbness and tingling of the little finger, part of the ring finger, and in the palm on the little finger side. Ulnar nerve compression at the elbow: This causes not only the numbness noted above but also numbness on the back of the hand on the pinky side.
See MD: Hand numbness likely is due to pressure on the nerve either from damage, inflammation or direct pressure. Throat sensation can be topical in nature - not likely lemon water, but excess acid could irritate it. This may also be nerve related. So, get to the MD and find out what is going on.
