Hello @spanning, I use Google and Google Scholar (https://scholar.google.com/) a lot in my searches and sometimes the results can be misleading and sometimes pretty scary. I try find articles that are done by reputable organizations and the latest written dates which is where Google Scholar helps a little because you can sort the search results links by year at the left. I do know that chemotherapy has a nasty side effect of neuropathy since it also damages nerves.

I have no medical training or background but I am a little surprised when I read that the neurologist prescribed gabapentin if you don't have any pain and just have numbness all over. The reason I say that is before I was diagnosed with small fiber PN my primary care doctor gave me gabapentin when I complained about the numbness in my feet and legs. It was only after a few weeks and no difference that I told her it wasn't working and she brought in another doctor who asked me more questions, found out I had no associated pain, and told me gabapentin doesn't do anything for numbness. This is when I had an EMG and a referral to a Mayo Clinic neurologist who diagnosed me with small fiber PN.

Here's a few references on chemotherapy induced neuropathy:

I'm tagging @artscaping and @jenniferhunter to see if they may be able to offer some suggestions for you.

@spanning, I’m not sure if it is an option for you but if it is, the Mayo Clinic is very good at diagnosing health issues that are difficult to diagnose. If you would like to seek help from Mayo Clinic, you can contact one of their appointment offices. The contact information for Minnesota, Arizona and Florida can be found here:
