Thanks for the information. I've had a look at the articles you suggested, it really is difficult looking at TENS as a treatment because there is so much conflicting evidence out there. Nevertheless, I'll tell him about it, and I will definitely recommend seeing a pain team. I know there are a lot of sceptics out there about EPA's, but in this case I can't really see the harm in giving it a go (unless the cancer becomes a contraindication for its use). You are a true educator, even on the holidays you've got me reading journal articles lol Thank you though, it has been useful.
