Oh, isn't it horrid! I woke up one morning and suddenly I couldn't pull on pants, turn door handles or drive without that shooting pain. I really hope it clears quickly and you have caught it soon enough to manage the early stages before it gets any worse. I found resting it as much as possible helped and definitely look at getting a wrist brace. It cleared up for me about a week before the birth but I have had to be careful not to flare it up again. When I start to get the tingles, I know it is time to give my hand a bit of a rest and so far have avoided getting to the painful stage, thankfully.
