I hope her knee will be fine. The only knee procedure I've had is a shot to make it work better. They forgot to tell me about the pain that shot can cause. The shot give was lucky I did not pull his head off his neck. But the shot was a miracle in helping the knee.
So sorry to hear of your loss. Best wishes on your hernia surgery in March. May the medical team have an outstanding good day, and all the nurses and techs be kind and nice to you.
I've had both eyes done. It takes about 45 - 1 hr to get ready. 15 minutes from start to finish. It is Amazing and does not hurt a bit. (unless the iv hurts when being but in.).
