Hello Lu2011!
Welcome to the CP forum!
Well I'm certianly no expert on these units, I will just say that I can see where they may be somewhat efficitve for joint pain. I think it interrupts the pain signal, so again I can see where it may help. It certianlly might be worth a try, but at $500 I can see your point. OUCH! (little pain joke)
I was thking that your Dr can script this, but again I'm just not sure about that.....or maybe the possibilty of Ins paying for it? You must be refering to one that the Dr's use, .....and also, there are units that can be bought on line at a much cheaper price, but I believe the Dr scripted one's are much better at the job, and have many more setting options.
I don't think I have really done you much good for an answer, but did want to "Welcome" you here!
We have a great support group, and I encourage you to visit and post as often as you like.
Take care!
