They showed us the TENS in our classes, and we all had a turn of it to see what it felt like. I loved the sensation so i was going to organise one but never got around to it. When i was in labour, my friend bought around a hand held massager and as soon as anyone touched me with it i was about to kill them! I hated the feeling of the massager on my back which was crazy cause usually i love it. So, lucky i didnt get the TENS cause i probably would have shot anyone that came near me with it!
