I hate to say this, but it really sounds like carpel tunnel. If you wrap it things will get worse. My husband had surgery for his two years ago, and is doing fine. The first step you need to take is going to the doctor and getting it x-rayed. They will be able to tell you if that's what it really is, and the good news is if it hasn't progressed too much you could go through physical therapy. I know if it is that it is so painful, and I have seen many studies that say pregnant women get it more easily. I do hope it is something else, but the way you decribe it, I don't really know of anything else it could be.
