Hi
I saw Dr Carden about 4 years ago but he suggested at that time just nerve block. I did a few years ago have a lidocaine infusion in my hometown with a different pain doctor. For me the lidocaine did not help but before I had tried the patches and they did not. Everyone is different so if you find relief in patch you may want to try the infusion.
I hate to say negative about drs unless it is extreme but I did not care for Dr C. I felt he was pushy,did not review my records,and did not listen. When I stated I had to think about the block which I did not have with him but later with someone else anyhow a few weeks later the nurse called to see if I decided and to offer a special price which really turned me off. I did not bring up anything about the price either so it was just odd. Again he may have helped other people and I have had bad experiences with some docs so why I am overly skeptical.
