Lacking the...: Sounds like one is lacking the ability to stop chewing on his thumbs. If one stops chewing on the Right thumb, and continues chewing on his Left thumb (as a way to satisfy his compulsion to thumb-chew), and the unchewed Right thumb becomes normal, then he has his answer proven. Otherwise, a dermatologist can help, with an exam.
