Pregnancy Thumb?

Ashley
Before I knew I was pregnant I started having terrible pain at the base of my thumb. The pain is much worse at night. I did some research and it sounds like it may be De Quervain's or carpel tunnel. Since I don't have an appt until halfway through August I've been trying to manage it on my own by wearing a thumb brace, especially at night. Has anyone else experienced this? Did it resolve after birth? 
Also, I've been having leg cramps. Imagine a very uncomfortable tingling in your leg. Again, it's a lot worse at night. Anyone experiencing this? I read that it happens most later in pregnancy but it's def happening to me now. Help, please!
