I used a tens machine after an accident and didn't find it helpful at all but I know some people use it during labour. Hope you get some relief!
I have a tens unit machine as well and I've really been wanting to use it but my doctor told me that it was off limits while pregnant to avoid possible injury to the baby.
I hope that you can get some relief of the pain soon because I know first hand how bad that pain is. Best wishes.
Thanks, its to the point I cant walk n having a 2 n 4 yr old.. makes it difficult... I want to cry. I have physical therapy to see if it will help but not till mid December.
