Better? The most that I can say is that it's different. I am not using a cane anymore, however. But, I still am aware of foreign body in my leg! LOL. It doesn't hurt much anymore, except when I stand up after being seated for a while.
My doctor says that when I forget all about it, it will be time to have the othe one done. It's been 3 months, and I'm not there yet.
I think you would need at least 6 months in between. My MIL had them done almost a year apart.
