Hi, hope you can get that appt. soon. Don't think that PN can't get better, it can. I have it in my left foot, ankle and calf. Last year I was in a wheelchair. This year I am walking alot better with no assistance. I started on suppliments (that I didn't believe in ) B12 shots etc. Have hope that with the right care and assistance, you can get better. Keep hope alive. ginnie
