Holy Smokes! Yes I have large fiber idiopathic PN and yes my handwriting is awful now. I would have never attributed to PN. I am old enough to remember Penmanship in grammar school, always got an A, push pulls and ovals, loved it! Anyone else remember that?Thank goodness I have no pain just balance issues. I am going on 10 yrs since diagnosis. I feel by exercising, taking supplements, correct shoes and inserts, tens machine for my feet have helped immensely. I take 300 mg gabapentin daily for the burning and tingling, it helps.I wish the balance issue would disappear, but I know better. I will continue eating a healthy diet and doing all things listed above to maintain. I am going to go do some push pulls and ovals!! Best wishes to all and never give up!
