Cortisone injections and other procedures

I am wondering if anyone has had any type of injections done such as cortisone and found relief. My stepmother is a nurse and spoke to her hospitals neurologist who said they have had success with cortisone injections. I have read NOTHING indicating this was helpful. I am also wondering about other procedures anyone has had that was helpful for type 2. I am currently doing the medication route and have been for many years with no success. I feel like if there is a procedure that may help put this in remission I would like to explore it rather than treat the symptoms with medications for the rest of my life. I want my life back! I have a referral to see a neurologist who specializes in tn and I need to be prepared. Thank you!
