If any horizontal lines can be felt on the nails of a hand (even if these are very faint), they tell of an emotional trouble in the recent past. Sometimes these lines (like dents) look to be coming up (convex) and sometimes they look a bit spoon like (concave). They are generally found very clearly in the thumb nails. They tell some emotionally troubling event in the recent past. Sometimes we really feel a strong hollow in the thumb nail. It indicates a traumatic event (like divorce, death of a relative or the loss of a job). Hand nails change completely in six months, so if these ridges last for more than six months it means that the person is still experiencing the pain of that event. These horizontal lines and dents can be felt most easily on thumb nails.
