When I was pregnant and I was about maybe 26 weeks pregnant, I started to feel my wrists getting like swollen and hurting every time I was working. I'm a dental hygienist so I thought I was using my instruments wrong or my ergonomics were wrong but I had talked to my doctor about it and she said that some women do get like carpal tunnel or arthritis I guess during pregnancy so I had to take some time off work before my 36 weeks.
