After having horrible back pain last night and being convinced I was in labour, I have decided to try and get a tens machine to help me deal with the pain when the time really does come. I have looked at Boots online, but can't see where it says you can hire a tens, and they seem quite expensive to buy. I used a hospital one with dd as I was already there being induced, and it was a big help, but I intend to stay at home as long as possible this time, so would like to have one to hand. Any suggestions?
