C6 C7 C8 finger numbness map
Original finger numbness map showing overlapping C6, C7, C8, carpal tunnel, and ulnar-nerve clues. Use it for discussion, not self-diagnosis.
New or worsening weakness, spreading numbness, hand clumsiness, walking changes, bowel/bladder symptoms, fever, cancer history, or significant trauma need prompt medical care. Night pain that keeps waking you, grip loss, or fast progression should not be handled only with online exercises.
