Welcome @davelobb12, Sorry to hear your neuropathy pain is getting much worse now after 3 years. The only fairly new one I'm aware of that shows some promise is the clinical trial for WST-057 (4% pirenzepine free base monohydrate) from WinSanTor.

The hope is that these new findings support the potential for select anti-muscarinic drugs already on the market, like pirenzepine, to be repurposed as a possible preventative, and even treatment, for the clinical effects of peripheral neuropathy, which, for patients, has been largely been a matter of pain relief, and associated with significant health care costs." — Blocking Anti-Muscarinic Drugs May Reverse PN: https://winsantor.com/anti-muscarinic-drugs-may-reverse-peripheral-neuropathy/
