Getting your nails done??

Okay so this might sound silly AF but my hands have been hurting SO bad and I’ve been having poor circulation which is always causing them to go numb... anyway, my sister told me to go get a manicure because it helped her (getting the little hand rubs) but then I was told not to get them done because you aren’t supposed to have your nails done while you give birth for some medical reason?? This sounds bizarre to me so I am just curious if any of y’all have heard that too??
