I do not have PD, but do have some battered nerves and some times use 2 Tens units. I wonder if any of you with PD have tried one. My husbands pain comes from previous injuries not his PD. If they worked he would need several. I might just try to get him to give the Tens unit a try. Medicare will pay for one. Sid do you have any idea or have your tried one. Nita
