Cubital Tunnel Syndrome

Has anyone been dealing with this during pregnancy? I can hardly sleep at night because I wake up in the middle of the night and my arm is painfully numb from my elbow down to the tips of my ring and pinky finger. I tried buying a brace to wear at night and I just woke up two hours later with a very swollen hand. Doctors say it should resolve after baby is born, but I have 11 weeks to go. Something's gotta give!
