I agree this is really a persoanl decision. I had one for full body RSD it was in for 3 years I just had it removed in Nov of 08. In my opinion it isn't designed for full body coverage. You are only covering one leg it might work for you. Ask how your posture will affect the strenght of the stimulation? My leads where the lenght of my spine and when I turned my head it would turn up the stimulation when I sat down it would turn it down. I was constantly adjusting the stimulation.

Make sure you understand the remote and how to change the strenght of the stimulation.
Ask your doctor on a scale of 1-10 (pain scale) where should your pain be if you proceed past the trial?

I was never told not to lift. I was only told not to have it on when I was driving. Mine was extremely sensative to posture.
I hope you get the relief you are looking for and that you will be able to continue to work. Giving up my job was as hard on me as accepting I have RSD.
May Gob Bless You!!
