Hi, I'm 31 weeks pregnant with my first child and just found out about a tens michine, just mentioned off hand in a what to pack in your hospital bag article. I'm staring my nct course next weekend so I'll be able to discus then. I understand that way it works, stimulating the nerve endings. But does it actually help? I am a healthcare professional and it seems like it might just numb the skin and not much deeper around pads. Saying that, I found though cooling strips for migranes really effective for numbing pain so maybe tens michine is simular for the lower back? What has people experience been? Do they often have them in birth centres or maternity wards or isn't something to buy yourself.
