Apparently some pregnant women get carpel tunnel during pregnancy, it goes away once bubs is born. That's what I've been told :)
If your are worried bout the numbness tho I would talk to your doctor...
At times I experience numbness in my arms/legs and sometimes even my face. I have episodes where I have sezuries/fainting like things. I get really dizzy and all these other things to. I was I hospital for it but they have no idea why it happens to me. Ive worked out myself that it happens when I do too much and especially if im dehydrated. I would suggest taking hydralytes they help to hydrate u really quickly. I hope this helps u out! Its scarey going numb
