I've been using a Cefaly tens machine for years now and it really helps when I have a migraine. When I came to use it the other day it wouldn't work, so I thought I would order another one. Well it's over £300 now and the electrodes are nearly £30. Way out of my budget at the moment. I had a look around and I've come across the Migraine Pain Reliever Tens from Lloyd's Pharmacy it's £40 and the electrodes are under £4 for 4. It looks exactly the same.
I just thought I would spread the word Incase it benefits anyone. Disclaimer, I haven't actually used it yet. I have no idea how to make a link.
