1 doctor agrees

In brief: Carpal tunnel

Fluid changes during pregnancy can produce nerve compression at the wrist c/w cts, which is benign and usually is gone a few days after l & d.
Persistent numbness could be associated with nerve pinching at the elbow, disc problems in the neck, thoracic outlet syndrome. But rarely left arm problems can be heart associated (quite unusual at your age.).
