Carpal Tunnel and related stress injuries struck me in mid-August and left me practically helpless for nearly 3 months. After 3 days of doing the stretching exercises in Butler's book, I was back to doing simple activities and completely off the high dosages of anti-inflammatories recommended by my doctor. I cannot recommend this book too highly. The exercises are super simple and can be done throughout the day whenever you have a moment - in front of the TV, while laying in bed, in the car at a stoplight. The exercises deal with the entire upper body, including arms and wrists. You can choose those appropriate to you and your activities. If you are not sure, Butler has a list of which exercises apply to certain lines of work. An excellent - and inexpensive - book.
