I used one in hospital for the birth of my first child, this was however over 20 years ago. I found it to be a very odd sensation and did give me something other than the contractions to focus on, however I can't say that it helped me as my labour was not long enough (just over 3 hours). I would say give it a try if you have a unit available, and good luck with baby no. 2
I used one for when I was in labour with my 2nd child, 4 years ago. Sat at home, playing on Playstation with the family whilst the Tens Machine was attached - I absolutely loved the sensation. It was so successful for me for removing pain that I very nearly ended up having my daughter at home because I wasn't particularly aware of how far into the labour I was. She was born within 30 mins - so for me it was extremely successful.
I hired one from Boots the Chemist for a very reasonable price. I hope this helps and all the very best to you.x
Quassia, my hospital's maternity unit loaned them out to women about to give birth! They've been used for a long time now as pain relief for labour pains - personally I didn't find it helped mind you, but they were recommended by the midwives.
I was in the chemist last week and their own radio station was advertising the tens machine, but gave the proviso that it should not be used during pregnancy or childbirth.
I would advise turning into a cat before giving birth. I have never seen a cat go into hospital before having kittens and have never seen one use a TENS machine.
