Nerve Decompression Surgery

Lydia has been very uncomfortable and in pain for many weeks now. She feels "pins and needles" as if her foot is asleep. But this like 100 times worse, to the point of being unbearable.  The surgeon says it's because the nerve was damaged during or after the surgery, or it's being pinched inside by something.  So, here we are again in surgery.  :(  Today they will open it up and release the pressure on her nerve which will hopefully ease her discomfort and we hope she will regain movement in her foot which up to now has been minimal.  I hate the idea of putting her through ANOTHER surgery, but there seems little choice.  Tim.
