OP: I should have included two other products I've used not many months after hip replacement and they helped the nerve damage issues. They are Inosine and Sphinglin and you can do research on them and amazon sells them of course. I'm about to buy them again as I still get recurring nerve issues in my thigh and down leg. When I took them I took them both at the same time, but do what you may feel comfortable with. I've talked about these here but haven't heard if others have used them.
