Just wondering on what your opinions are on a TENS machine? Do you think they do help in labour? Or a waste of money?

This is a first I've heard about TENS machine and this is the summary of what I understood from different articles online: TENS stands for transcutaneous electrical nerve stimulation. It consists of a hand-held controller connected by two sets of fine leads to four sticky pads which are placed on your back. The machine gives out little pulses of electrical energy that reach your skin via the leads and pads. The pulses may give you a tingling or buzzing sensation, depending on the setting. If you don't want to hold the controller, you can clip it to your clothing or attach a strap to hang it around your neck. I guess it's a good option to try if you can't tolerate pain but don't want to get an epidural. You can apparently rent them from hospitals so speak to your gynaes about it if you are keen.
