Have any of you tried a TENS unit? It's a little oval
box like thing, size of a phone,with leads that have
rubber pads on end. It works by battery which gives
a pulsating effect where pads are placed on skin,
which stimulates the body's own pain killer, endorphins. You will get one in any big drugstore/
chemist at pain counter. I wouldn't be without one,
as they're great for any sprains,back problems,etc.
