Have any of you ladies heard of using a TENS machine during labor? You attach these patches, that are connected to te machine, to your lower back and when you have a contraction you turn on the machine and it sends electrodes to your back that feel like pins and needles. It's supposed to increase your pain tolerance during the contractions. They have special maternity ones that have larger pads, but I had to use one in physical therapy after I had knee surgery to help with my exercises of my leg. Its a definite pins and needles feeling but it does help distract from the original pain that your having so that you can get thru whatever you're having to do. I had never heard of using it for labor, but I was looking through another pregnancy blog earlier and someone was asking about using one. They're actually pretty cheap to rent (you can rent thru a maternity supplies website).
