grandmael -- Wow...four miles a day. Impressive! I have trouble with 4 blocks. Wanted to let you know that due to my poor balance, my neuro doc has put me in physical therapy to hopefully improve my balance. I go to PT 2 days a week and my physical therapist feels that after 5 weeks, he is seeing small signs of improved balance. I don't see it but he does, my exercises are geared towards balance deficiencies. It isn't easy but I will continue on because many of us with PT, as you know, the fear of falling is concerning. I feel virtual support groups are helpful and Mayo Connect has given me the ability to communicate with others having similar effects from PN. I've learned a lot from this site and THANK YOU TO ALL OUR MENTORS!!!
