I'm scheduled to have the diagnostic test done next Thursday and if it works they will book me for the radiofrequency ablation. It will be done to my C4C5 in my neck. I have foraminal narrowing with nerve compression and a couple herniated discs. I had an epidural done there before with steroids and no relief. So this time it will be the diagnostic test with anesthetic. I'm even very nervous about the diagnostic test since I didn't handle the epidural very well i got so nauseated during the procedure and of course you can't move an inch. He can't give me anything to relax me since I must be fully awake to help determine any pain relief. I've been going for lidocaine and ketamine infusions for over 1 year every 2 months and lately they haven't been giving me any relief. I hope this really helps but very nervous and would appreciate any info on others how have had this done.
