I brought a tens machine which i want to use now that I am in this prolonged unestablished labour stage at home. Id only used my tens machine for one night when already the pads have lost their stickiness and one has fallen off! The replacement pads are quite expensive at £7 a pair. What did other people do about this? I know it sounds silly question but can you stick over the top with plaster or selotape? I have a long way to go yet and need my tens! Plus im on my own today and cant get to the chemist even if i wanted to!!
