Hiya - my daughter is 33 weeks pregnant and is in constant pain with sciatica - she has been in hospital twice in the past 2 weeks but the only thing that she has been offered is codeine. She doesn't want to take this unless she really has to - we have been talking about using a tens machine, Mama+ is the one we are looking at. Has anyone used one recently - can she use it at 33 weeks? Please share your thoughts/experiences - thank you
