Wow, I am so sorry you had those bad experiences. I have had numerous nerve blocks and ablations and they were nothing like that. Mine we all done with conscious sedation, either Versed or propofol. The only pain I felt was a small prick for the numbing medication he used to prevent pain from the big needle. They were all done under fluoroscopy where the doctor can see exactly where he is going and what nerve he is targeting. Maybe you need to find a more qualified doctor.

I agree they will not cure anything but they can make you comfortable until surgery becomes absolutely necessary.
