BabyBee said:I'm not quite a mummy yet... but they send little electrical pulses which (being technical) ease the pain. Lol. My OH's mum uses one for her bad knee and she loves it! Except when she turned the voltage up a bit and shocked her leg a little. Lol.
I'm hoping to borrow it when i go into labour - though obviosuly for when i'm not in the water.
