Sorry to hear that the DRG was unsuccessful for you. I had a 5 day trial a few months back. It did cut the pain in half during the day time but I don't think it helped much for the evening. So, as of yet I haven't had the permanent one put in. The 3 people who had success I talked to had a different doctor than the one who did my trial. Perhaps, success depends on the skill of the doctor who places the leads in the DRG. I have lower back pain too. I might have an epidural injection on Thursday in the lower back possibly @ L4, L-5. They are the nerves that service the toes of the foot. Perhaps that could help alleviate the pain I have in the toes from two prior surgeries I had on the toes.
