I am so glad that you got good news...what a relief! Carpal Tunnel can be so painful and irritating. I have had issues on and off (when I knit too much) with CT and recently bought the wrist supports. I sleep with them on. They did take a bit to get used to, but they have stopped me from waking up from numb hands during the night. They also have helped me throughout the day too with few symptoms. The good thing about pregnancy induced CT is that it typically goes away after delivery.
Please keep in touch with us and let us know how things are going. My best to you and your wife!
