When my problems arrived 2004-2007, I had ablation for C34-C56. None of the ablation lasted. On the last ones a month ago, I said I had ablation around 42. DR says the nerves are more likely to grow back in a younger person. I'm 64 now and will see how long it lasts. I think fusions are the only way to kill it for sure. I'm currently fused in the middle and will continue ablations because I don't want my whole neck fused. I had the fusions but still pain, got pain implant with a battery, tens unit time. The leads themselves stopped migraines but if I used the battery on the implant it would buzz on my nerves and had a migraine in less than 30 minutes so could never use as planned but freaky enough those leads placed at 3 levels stopped the daily excruciating migraines daily
