@charlieg304 So sorry about your PN and the consequences for your active lifestyle. I am in a similar situation: started to run marathons in 2013 after the Boston Marathon bombing and crossed the finish line 11 times since then. First Covid infection in 2022 and second one in 2024 while having all Moderna mRNA Covid vaccinations. Diagnosed with idiopathic axonal polyneuropathy in 2023, but symptoms started earlier. I was still able to run the Chicago Marathon in 2024 by managing my PN, but had to drop out this year after multiple issues in my right foot. It is complicated because my spinal stenosis comes into play as well. In my case, keeping my core strong and train my brain to deal with the loss of signals coming from my feet is my hope.
