I'm needing some help and my community midwife is basically a waste of space. I'm 31 weeks and since 16 weeks Iv suffered so badly with back pain/ sciatica that it's got to the point I can lay/ sit/ sleep or walk for long.  I asked to see a physio and was told there was a huge waiting list and I will have most likely had baby by the time I'm seen. I have tried everything I can think of and can google lol but Iv read so many mixed review on using a TENS machine for the pain. Some say it's ok to use some say not before 37 weeks I just need someone to tell me it's safe or it's not for definate as I really don't want to bring on labour. Can anybody help me please????? 😫
