My pain specialist says I have nerve damage and so my mouth pain will take years to go away. He wants to do a glossopharyngeal. nerve block followed by a nerolitic procedure. The doctors intentionally damages the nerve so the possibility of no pain. Unfortunately, the proceedure kills another salivary gland(I already have extreme dry mouth), it causes less taste and makes your heart beat faster. The last downside is that sometimes it can make the pain worse. Any comments or experiences. I'd really appreciate it.
