I have to totally disagree with Kelly's post. Have you actually used one yourself in labour Kelly?

I used a TENS machine for my birth and found that this was the only pain relief I required. Yes, you do focus on the contractions but how can you ignore them? I found the TENS actually helped distract me from the pain, so much so that I did not even ask for gas or any other kind of pain relief. I used the TENS in both early labour and during the pushing stage - hence it's usefulness throughout the whole labour. It was also great to use in the car on the way to the hospital. Also, I found it easy to remove and replace when I went in the bath/shower. PersonaIly, I couldn't have made it through my labour without drugs if I did not have the TENS machine. I highly recommed it's use and I will be hiring one again for my next labour.

I would have thought this website would be promoting all methods to reduce the use of pain medications in labour (even if the particular method does not work for everyone).
