OP: My right foot is really numb and my injury was from hip replacement 10 yrs ago so for me it's arthritis that has set in...my whole right side of body from replacement is a mess.

Left foot is a little numb from time to time and again it's arthritis...

My right and left side of body is like day and night pretty much. Surgery is very invasive, so just like other injuries.

I use Topricin a lot and find it best for my issues and also Ultra Tiger Balm and use both these on especially right foot and bend and rub my feet a lot. I k eep my feet lubricated day and night and of course wear socks.....

And a lot is from nerve damage too.
