Welcome @bobc2, I'm sorry to hear your symptoms have rapidly increased in the last 8 weeks. The Foundation for Peripheral Neuropathy has a list of treatments here - https://www.foundationforpn.org/treatments/, along with a list of commonly prescribed medications for nerve pain here - https://www.foundationforpn.org/wp-content/uploads/2016/10/Medications-Updated.pdf.

Have you discussed the increase in pain since starting the treatment with your neurologist?
