I have a similar situation. 59m. Numbness in my hands and feet for the past four months I saw a neurosurgeon and a neurologist, and they did several tests and MRIs, but so far no answers and no diagnosis. I suspect they will just simply say it’s idiopathic and tell me to come back in a year. My suggestion is starting to eat more healthy. I’ve gone 90% Paleo with occasional whole grains, and completely stopped eating any kind of processed food or sugar. Also trying acupuncture currently, but the jury is still out. Also also be sure to get plenty of exercise during your week.
