Hello @jzxbb, Welcome to Connect. I know it must be difficult managing the pain. I'm sorry to hear that the Sanexas treatments didn't provide any relief. I'm not sure if you are aware of the Foundation for Peripheral Neropathy but their site may provide some helpful suggestions here - https://www.foundationforpn.org/living-well/.

You mentioned chronic undiagnosed pain with peripheral neuropathy. Have you thought about seeking help at a teaching hospital or major health facility like Mayo Clinic?
