Hello @graziellaz, Welcome to Connect. I will be 82 later this month and have had neuropathy that started gradually in my toes, then into the feet and legs over the years. I don't have any pain, just the numbness and some tingling so there isn't much that helps except to stay active and possibly work on strengthening the legs (just my humble, non medical opinion). There is another discussion that you might want to scan through to learn what others have shared:
-- Neuropathy symptoms come and go - is this typical?: https://connect.mayoclinic.org/discussion/neuropathy-symptoms-come-and-go-is-this-typical/

The Foundation for Peripheral Neuropathy has a lot of helpful information on living well with neuropathy that might be helpful - https://www.foundationforpn.org/lifestyles/. The also have quite a few webinars on learning more about the condition which I've found helpful. Here's one that I watched last year that was helpful - Session 5: Living Well with Peripheral Neuropathy: Enhancing Quality of Life - https://www.youtube.com/watch?v=xkRvvaK4_1s

You might want to write down a list of your questions and concerns to take with you to your husbands upcoming appointment with the neurologist to help you get some answers. I find that if I write my questions down that I'm more likely to not forget them when talking with the doctors. Has your husband tried different shoes to see if that might help with the walking?
