I am 20 weeks and I am having difficulty sleeping. When I sleep on my right, I wake up to pins and needles in my right arm. The same thing happens when I switch to my left. I've been told this is carpal tunnel. I am a chef by trade, working on my feet 9.5-10 hours a day, five days a week. Is this happening because of my demanding job and use of my arms? Do any of you lovely mamas have any suggestions for a better nights rest? Thank you!
