Can a c4 disc prolaps causing severe headaches be cured without decompression surgery?

Possibly: A cervical disc problem can cause headaches. These are known as cervicogenic headaches. A cervical disc herniation can potentially heal over time. Also, some disc problems don’t necessarily “heal”, but their symptoms can potentially be managed nonoperatively. Radio frequency ablation is just one example of a nonoperative procedure than can potentially “cure” headaches coming from neck.
