Has anyone tried these? I had the worst back pain for both labours and the midwife offered them to me while I was in labour with DS - I had never heard of them at the time and it was all a bit too much to agree to when I had not looked into it previously. I was also afraid if the back pain goes-I'll have no distraction for the horrendous pain I was having at the front. I am thinking of them for this labour but I have heard they REALLY hurt! which sounds silly when you compare it to labour pain but it's still putting me off a bit! So - if you had them what did you think?
