Nerve ablation is a mixed bag. Though I can’t speak to your specific case, I’ve known people who tried nerve ablation to reduce pain, & for them, it was minimally successful i.e. either didn’t relieve the pain to the expected extent, or if it did, the relief didn’t last very long. That said, everyone is different so it could be a great benefit for you. If you elect to have ablation done, go in knowing it might not be a magic bullet.
I think the information @Leah gave you in (Severe Trap and Neck Pain - #2 by Leah) has some really insightful information that’s worth pursuing before you seriously consider nerve ablation.
