Hi Hong, I would like to add my welcome to Connect along with @celia16, @rollo8, @nayers and others. Hoping you get some answers at your meeting with the specialist (neurologist?) next Tuesday. The best thing you can do to help yourself is learn as much as you can about the condition and become your own best advocate. The Foundation for Peripheral Neuropathy has a lot of helpful information for newly diagnosed folks, including causes and treatments - https://www.foundationforpn.org/newly-diagnosed/.

You mentioned you didn't have any nutritional deficiencies. Vitamin B6 can cause neuropathy symptoms if you have high levels in your system. Do you take any supplements or drink a lot of energy drinks that contain Vitamin B6?
